2. Introductions

DD Goodman introduced D2 management team, and relayed special apologies from AD,Guy Vandermeersch and new Editor, Jim Gardner, who were not able to attend this meeting.All the participants introduced themselves.

3. Approval of Agenda

DD proposed adding two items to the agenda of this meeting previously distributed(Attachment 1). DD proposed to add a new item as 7.1 on ILV, and to change item 11.3 tobe a discussion on Div.2 website links, including database on optical radiation properties ofsources, detectors and materials. The agenda with these changes was approved.

4. Approval of the 2003 D2 meeting minutes

The minutes of the 2003 D2 meeting in San Diego, USA, which were distributed via e-mailcircular and on the website in September 2003, were approved with no changes. DDexpressed her thanks to Secretary for always preparing very complete and comprehensiveminutes.

5. Director’s Report (T. Goodman)

The joint Symposium on LED Light Sources, held this time in Tokyo, was very successful;94 participants registered for the event, demonstrating the continuing high level of interestin the subject of LEDs. A follow-on symposium on the same subject will be planned in afew years.

John Moore (UK) stepped down as Division Editor at the end of the last quadrennium(2003), and Jim Gardner (CSIRO, Australia) has taken over the position. He has alreadybeen working on the ILV and in future all documents (TC reports, etc.) to be publishedshould be sent to him. DD further recommends that TCCs send their draft documents to theEditor when they are near completion and certainly before TC ballot.

DD reported a few issues from the Board meeting held after the San Diego session in 2003:

a) New policies and procedures for publication salesThese were agreed by CIE BA and have already been introduced. CIE publications can nowbe purchased directly from CIE CB as well as from NCs. The prices are the same whetherordered from CIE CB or any NC. Arrangements have been made so that the income fromthe sales (when ordered from CIE CB) are credited to each NC depending on which countryeach order came from. DD encourages everyone to order from CIE CB, which is bothquicker and less trouble for CIE (no shipping to NC). It is also planned that publicationsales will shortly be possible directly via a website and optimum methods for this are beinginvestigated. DD asked whether anybody had purchased publications recently in the newway. Ohno reported his experience that the ordering process was very smooth andpublications were delivered from CB very fast (in one week). Kohmoto experienced thesame in Japan. Several people mentioned that it is additional advantage that credit cardpayment is accepted. Rattunde indicated that he has an arrangement with the German NC sothat when new documents come out, these are sent to him automatically. DD suggested thatsuch an arrangement might be made with the CIE CB (at least, to notify people when newpublications are issued). She will suggest this at the next CIE BA meeting. Gibbs mentionedsome difficulties associated with the CD ROM of all current publications and the very highon-going costs for this. DD will raise this as well at the next CIE BA meeting.

Johnson suggested that it would also be useful to have the list of current publications andabstracts (with prices and ordering information) available for electronic distribution. Thereare already some pages on CIE website containing this information, but there is a need tomake it more easily available. It was agreed that Secretary will post, on D2 website, anannouncement of the new method for ordering publications that is now in place. DD alsoadded that NC members have large discounts on prices of publications, which is one of thebig benefits of being a NC member. Bergman (President of CIE-USA) suggested that itmight be a good opportunity to invite new membership when orders come from a non-member. For example, an invitation to join the appropriate NC could be sent together withthe ordered publications or, when the website for direct ordering of publications is available,this could be linked to the membership application page of the relevant NC website. DDagreed this is a good idea and will suggest it at the next CIE BA meeting. It was noted thatthe fees for NC membership are still different and are at the discretion of each NC. The feescannot be harmonized due to the different ways and budgets under which different NCsoperate.

b) CIE HandbooksJohnson asked about the new form of publication that had been discussed at previousmeetings, namely compilations of CIE publications on given topics (‘CIE Handbooks’). DDsaid that there has been no progress on this, due mainly to the costs involved in binding thepublications in book form. Johnson pointed out that technology is available for publishingbooks in small quantities at low cost and suggested CIE should investigate this further. DDwill raise this at the next CIE BA meeting.

- 11 -

c) Revision of CIE PublicationsA number of current CIE publications have old dates, which might make people feel thesedocuments are outdated. It was therefore suggested at CIE BA that each publication shouldbe regularly reviewed (e.g., every five years) to determine whether it is still current, and, ifso determined, it could be re-dated with the latest review date. This will be discussed againat the CIE BA meeting in September. DD asked for comments from participants, either atthe meeting or later, by email. Bergman suggested that, as is the case for ANSI, anydocuments assigned new dates in this way should say clearly whether the latest version is are-affirmed version or a revised version, so that those who already have the previous versionknow if they need to buy the new one. Gibbs mentioned that care should be taken ifoutdated publications are withdrawn, because they may be still referred in other publicationsand people may still need them. Johnson commented that such a process of periodic reviewis done within ASTM by balloting and suggested that a similar procedure should be carriedout within CIE – in particular, the review should be done not by just one person but shouldinvolve a formal ballot process. Sauter commented that, if such a ballot process is put inplace, ample time should be allowed (e.g., half a year) for NCs to review the documents.Johnson added that if an old version is either scanned or retyped and reformatted forelectronic circulation, it should be assured that the new version is an exact replica of the oldversion. DD will forward these comments to the next CIE BA.

d) Supportive MembershipNew categories for supportive membership of the CIE have been agreed – full details are inthe latest CIE membership brochure available from CIE CB.

e) CIE AwardsA new award category, Distinguished Services Award, is to be introduced as part of the CIEAwards scheme. About three people will be selected to receive this award in eachquadrennium. Nominations will be considered by a committee comprising of President, PastPresident and President Elect.

6. Secretary’s Report (Y. Ohno)

Country Members: D2 now has 37 country members, with a new country (Czech Republic)added during the past year. The country representatives of Belgium, China, and India haveall changed since last D2 meeting.

Reports Issued: The Summary of the 2003 D2 meeting (San Diego, USA) was distributedvia e-mail circular in July 2003. The Minutes of the San Diego meeting were distributed inSeptember 2003. The Activity Report – May 2004 was produced and distributed in May2004. These documents are also posted on the D2 website.

Division 2 Mailing List: The List now has 187 persons (last year – 161). The e-mail list isalways kept updated as much as possible. Currently 182 persons have valid e-mail addresseson the List. All communications in D2 are done by e-mail (reflector) and through the

- 12 -

website (except for a few country members who have no e-mail access). The Secretaryrequested to everyone to inform him any changes of e-mail address as they occur, to ensurethat they continue to receive circulars.

Division 2 Website: As a countermeasure for ever-increasing spams, all e-mail addresses inD2 Mailing List on the website have been removed and they are made available only withpassword protection. The current e-mail addresses are found in the Subscriber List of theCIE-D2 email reflector, which can be accessed by username: cie2, password: vienna. Itshould be noted that the list is not in alphabetical order. Names can be searched on thebrowser.

TC Drafts on Website: Secretary also maintains all the latest TC drafts on the website (asmuch as possible). Currently 17 TC drafts are posted. He reminded everyone that theblanket password is distributed only to CMs, and that passwords for each individual TC aremade available to TC members (from TCC). Those CMs or TC members who do not havepasswords can contact Secretary or TCC to receive the passwords.

E-mail reflectors: CIE-D2@nist.gov (address is now hidden on the website) is used for D2circulars and for discussions on Division-wide issues. Junk mails and spams are filtered outby Non-subscriber block. Only messages from registered subscribers are distributed. Anarchive of all the past messages is available. E-mail reflectors are also available for all TCs,although currently only four TCs have reflectors (TC2-45, 46, 48, 29). Secretaryencourages other TCs to create and use e-mail reflectors to discuss their draft documentsbetween physical meetings and thus speed work progress. To create a reflector, simply senda request to Secretary with updated member list. A good example was TC1-48 (revision ofCIE 15.2) where most discussions on the draft and decisions were made by e-mail.

Organizing meetings: Secretary worked as a member of the organizing committee for theLED symposium held this time and also organized the TC meetings.

DD Goodman expressed her thanks for the continuing hard work done by Secretary, whichwas enthusiastically endorsed by everyone present.

7. Editor’s reportThe new Editor, Jim Gardner, sent a report to the Secretary. Except for the work on the ILV(reported in next section), all the editing work taken by the previous Editor (Moore) wascompleted before the transition, and therefore no documents and materials were transferredto the new Editor. An informal meeting was held with Editor and most of D2 ManagementTeam (DD, Secretary, AD Johnson) during the CORM meeting in May, at which the ILVwas discussed. The Editor is currently working at NIST as a guest scientist and will staythere until the end of October.

<Noted after the meeting>The TC2-22 report (Intercomparison of Measurements of the Luminous Flux of High-Pressure Sodium Lamps) that Moore worked on for final editing has been published as CIEPublication 153: 2003.

7.1. Revision of ILVSecretary reported on the status and recent work done by the Editor on the revision of ILV(Division 2 terms – Sections 1, 4 and 5). The draft of the proposed revised and new termswas voted on by the Division in June 2002. There were a number of comments from theballot, but no actions had been taken before the new Editor took over. There had been somedelays due to difficulty communicating with the previous Editor, but all relevant material,including the draft and the comments from the ballot, were subsequently retrieved from theCIE CB and sent to the new Editor, who wrote proposed actions for all the comments.Several new terms for incorporation in the ILV were also proposed in the TC2-25 final draft(Zwinkels) that has been approved by Division ballot. From these materials and actions,Editor prepared the following four documents:

- Response to the comments from the ballot- Proposed changes from the current version of ILV:1987- Proposed new terms to be added to the current ILV- TC2-25 approved terms.

These documents were reviewed by Secretary and DD, then distributed by an e-mail circularon May 26, 2004 requesting that any objections to the changes be sent to the Editor byJune 9. This short deadline was due to the final deadline for submission from each Divisionto CIE CB by the end of the month, and Secretary apologized for the short notice. Noobjections or comments had been received.

There were several terms that Editor indicated should be discussed at the meeting. DDGoodman asked the participants for comments on the following terms, and decisions weremade as follows:

01-28 quantity of light - proposed change agreed (luminous energy; quantity of light)and corresponding change to 01-43.

04-73 gloss (of a surface) - keep definition as in present ILV05-42 (non-selective) quantum detector - keep definition as in present ILV but add note

to say that it should be stated whether the internal or external quantum efficiency isbeing considered; if not explicitly stated otherwise, it shall be taken as being theexternal quantum efficiency

<new term> array detector - this term not to be included.<new term> polychromator - add this term, together with “monochromator” which is

currently not defined (to be finalized after the meeting).

DD asked participants whether there were any objections to the other proposed changes. Noobjections were raised. DD stated that, if participants have any objections noted later, theymust be received by the end of next week (June 18) or they could not be considered.

AD Johnson raised a question on general policy whether all the terms approved in technicalreports should be included in the ILV (e.g., as for TC2-25). The general guidance is thatterms used only in very specific applications should not be included, but there are no clearguidelines on how this judgment can be made. There was a lengthy discussion on how theline can be drawn between “widely used terms” to be included in ILV and “specific terms”that are not, but no good solution was found. It was suggested that, at least, an index of

- 14 -

terms that are defined in technical reports but not in the ILV might be useful. There was alsoa suggestion to have index for each section. It was also mentioned that the current versionhas four languages together, which makes it more difficult to look up for people whonormally use just one language. Separate volumes for different languages might be useful.DD answered that ILV is to be made available electronically, so it will be flexible and theseissues should be able to be handled. DD will carry these comments to Christine Hermann.

Johnson also raised a concern that a lot of suggested additions and amendments have beendeferred until the next revision, but it is not known how soon the next revision is planned.DD answered that ILV will be published electronically and will be revised more frequentlythan before. She agrees that it should be kept updated at much shorter intervals. Bastiementioned that D6 have submitted their suggested revisions and additions, some of whichare related to D2, but these have not been reviewed by D2. DD answered that submissionsfrom all the Divisions will be collated and the entire ILV revision may then be sent for NCballot, where there will be an opportunity to review terms of other Divisions. If there is anobjection relating to any particular term, no change will be made and the existing definitionwill be kept. Sauter suggested that at least six months would be needed for such a ballotprocess since the document will have to be sent to various groups within the country forreview. DD will send to CIE BA a request for a longer time for the ballot process. Johnsonalso suggested that reminders should be sent monthly till the deadline of the ballot. DDanswered that CB is already trying to do this.

(After the meeting, DD communicated to the D2 mailing list via email for any furtherobjections or comments on the proposed changes described above. With a few commentsreceived and discussed by email, the final version of the Revision of D2 Terms wascompiled and sent to CIE CB on June 29, and this work is complete.)

8. Progress reports from Technical Committees, Reporters, and Liaison persons

8.1. Associate Director Johnson and TC chairpersonsReports on TCs 2- 17, 19, 25, 28, 32, 35, 39, 42, 44, 51, 53 were given.

8.2. Associate Director Sauter and TC chairpersons Reports on TCs 2-04, 16, 29, 37, 40, 43, 45, 46, 47, 48, 55 were given.8.3. Associate Director Vandermeersch and TC chairpersons Reports on TCs 2-23, 24, 49, 50, 52 were given.

The reports given for 8.1, 8.2 and 8.3 are summarized below in the numerical order of allthe TCs.

TC2-16 Characterization of the performance of tristimulus colorimetersChair: M. L. Rastello (Italy) AD: SauterML: Denner (South Africa), Goodman (UK), Hengstberger (South Africa), Moore (UK),

Muray (USA), Ohno (USA), Rattunde (Germany), Robertson (Canada), Sauter(Germany), Schanda (Hungary), Steindl (Austria), Terstiege (Germany)

TR: To produce a report recommending methods for assessing the performance oftristimulus colorimeter heads for measuring chromaticity coordinates.

- 15 -

ST: DD reported that the TCC had planned an editorial meeting in Tokyo but could notattend. The TCC stepped down as she could no longer continue the TC work. JanosSchanda has agreed to take over the TC to finish the TC report draft and to go throughthe ballot process. The change of the TCC was agreed by voting with no objection.

TC2-17 Recommendation for integrated irradiance and spectral distribution of simulatedsolar radiation

Chair: G. Zerlaut (USA) AD: JohnsonML: Aydinli (Germany), Goodman (UK), Ignatiev (Russia), Justus (USA), Kaase

(Germany), Kasten (Germany), Kok (South Africa), Wilkenson (Australia)TR: Revise and update CIE Publication No.20 (1972)ST: A new TCC was agreed in San Diego, who has an ambitious programme for

progressing this TC. However no report was received this time. AD Johnson willcontact the TCC for the status.

TC2-19 Measurement of the Spectral Coefficient of RetroreflectionChair: N. Johnson (USA) AD: JohnsonML: Arens (USA), Brekke (Norway), Fisher (USA), Hsia (USA), Hubert (France), Kurioka

(Japan), Price (UK), Rendu (France), Rennilson (USA), Richey (Germany), Schreiber(Germany), Sugiyama (Japan), Terstiege (Germany), Vandermeersch (Belgium)

TR: Identify the critical measurement parameters, tolerances, and requirements for, andconduct an international intercomparison of, the spectral coefficient of retroreflection.

ST: Report given by the TCC. The draft is nearly ready for TC ballot. The main outputfrom the measurements is chromaticity. Several specification standards specifychromaticity limits and these mean that some revisions are needed to the report to takeaccount of these limits and the associated measurement uncertainties. There is a stronglink with D4 on surface colours for signalling and it had been anticipated that limitswould be added to the relevant documents for retroreflective surfaces – this will befollowed up at the D4 meeting in September.

TC2-23 Photometry of Street-Lighting Luminaires.Chair: G. Vandermeersch (Belgium) AD: VandermeerschML: Bedocs (UK), Lewin (USA), Rattunde (Germany), Por (France), Rossi (Italy), Gibbs

(UK), Pierson (Belgium), Blochouse (Belgium), Corrons (Spain), Andersen (USA),Nederpel (Netherlands), Ottosson (Sweden), Stratford (UK), Ikeda (Japan) – updatedJuly 2003.

TR: Prepare a technical report on the photometry of street lighting luminaries.ST: The TCC sent a report before the meeting with his apology for absence. He plans both

TC2-23 and 2-52 meetings in September in Brussels or France. TC2-23 has not metyet, but the TCC nominated a secretary Miss Blochouse from Shreder Company. Afirst draft is being prepared for the September meeting. These two committees willalso meet in Spain next year. TC2-52 should then be disbanded. The reportership (R2-30) on TL-5 lamps ended in San Diego. Since then the TCC had a meeting withinterested people and, as decided in San Diego, new recommendations will beincluded in an amendment of publication 121. The work will be done within TC2-23.

TC2-25 Calibration Methods and Photoluminescent Standard for Total Radiance FactorMeasurement

Chair: J. Zwinkels (Canada) AD: JohnsonML: Bristow (Sweden), Erb (Germany), Leland (USA), McCamy (USA), Nayatani (Japan),

Puebla (Germany), Racz (Hungary), Simon (USA), Witt (Germany), Clarke (UK) -revised Aug. 2002

TR: Prepare a CIE report on methods for measurement of total radiance factors ofphotoluminescent materials. Recommendations for realizing and calibratingphotoluminescent standards by the one and two-monochromator methods will beincluded.

ST: Report sent from the TCC prior to the meeting. The TC last met in June 2003 in SanDiego, in conjunction with the Quadrennial meeting. The TCC has largely completedthe revision of the TC report, incorporating the recommendations from this meeting.Due to other pressing commitments, this work was not completed by the target date ofOctober 2003. The new target date for completion of this document (Draft 12) andsubmission for Division ballot is October 2004. The fluorescence vocabulary termsfrom TC 2-25 were sent to the D2 Editor for inclusion in the revised ILV.

TC2-43 Determination of measurement uncertainties in photometry.Chair: G. Sauter (Germany) AD: SauterML: Bastie (France), Corrons (Spain), Daubach (USA), Ellis (USA), Gaertner (Canada),

Goodman (UK), Moore (UK), Ohno (USA) - Aug. 2002TR: To prepare a CIE recommendation as the basis for the determination of measurement

uncertainties valid for selected quantities used in photometry.ST: Report given by the TCC. The TC had a meeting in Tokyo on 9 June with many

participants. The draft is basically completed, although format of the worked examplesand possible calculation templates are still to be finalized. During the TC meeting theTCC proposed that uncertainties of the spectral values should be considered in thecalculation of distribution temperature; i.e., the differences between two curves shouldbe weighted by the inverse square of the uncertainty value of each point in order toobtain the best estimate (based on statistical theory). Ohno raised a concern that thiswould be a change of the definition given in CIE 114/4, and that, if this change wasrecommended, it would be possible to obtain two different answers from the samespectral data, depending on whether weight is applied or not. This would cause seriousconfusion. After a lengthy discussion, it was agreed that this recommendation (toweight the spectral values according to the associated uncertainty) should be includedin the TC draft, and also that a recommendation should be made to add a note to thiseffect in the revised ILV. After the TC meeting, however, Ohno noticed a problemthat the use of weight would give unreasonable results if the uncertainty values aremuch smaller than the deviation of the SPD curve from Planckian (see exampleEXCEL sheet – posted on the website). This issue was raised again in the D2 meeting,and as a result a reportership was established (see 10.2).

TC2-44 Vocabulary MattersChair: J. Gardner (Australia) AD: JohnsonML: Billmeyer (USA), Burghout (Netherlands), Ionescu (Romania), Johnson (USA),

Webb (USA), Young (USA) – Jul. 2000.TR: Revise CIE Pub. 127 to include improved definitions of quantities and methods of

measurement for total flux and partial flux of LEDs and to re-evaluate other partsincluding spectral and color measurements of LEDs.

ST: Report given by TCC. The TC met on June 10, 2004 in Tokyo, attended by about 40people. Draft 4 was prepared by the TCC and Ohno and distributed in December 2004.The new draft has a lot of additions as compared with CIE 127, including newmethods for evaluating the V(λ) match of photometers, the definition of Partial LEDFlux, recommended geometries for integrating spheres, introduction of the use ofspectroradiometers for photometric measurements as well as color measurements, etc.At the meeting in Tokyo, some of the new additions were discussed. There was aproposal by Schanda for another method for evaluation of the V(λ) match ofphotometers (presented at the Symposium), in addition to the two methods alreadyproposed in the draft. Attendees seemed to prefer Schanda’s method to the other twomethods. The TCC and Ohno will investigate this method further. The TC alsodiscussed the Partial LED Flux and agreed on the definition in the current draft. Therewas not enough time to discuss other parts of the draft. The TCC requested furthercomments on Draft 4 by e-mail within four weeks (middle of July) to produce the nextdraft.

TR: Produce a technical report for photometric measurements of flashing light, includingderivation of the photometric quantities applied to flashing light, measurement of lightsources, and calibration of photometers for flashing light.

ST: The report was given by the TCC. The TCC apologized for little progress of this TCfor the last two years. At the 2002 meeting, the focus was on the definition of effectiveintensity and standardization of the formula, which would need further visualexperiments coordinated with D1. The TCC, however, has not found any member orgroup that plans to perform such experiments. Rattunde suggested that the TC shouldnot wait for further experiments but rather complete the TC report with the currentknowledge available, without recommending a single method for effective intensity.The TCC agreed with this suggestion, but emphasized that there is a strongly need fora standardized definition for effective intensity.

ST: Report given by the TCC. The TC met on June 10, 2004 in Tokyo, attended by about25 participants. G. Sauter announced his resignation as the TC chair and introduced J.Schuette as the proposed new chair. The change of the TC chair was approved byvoting within the TC with no objections. The new chair ran the meeting. The TCdiscussed the issues to be addressed. It was agreed that many properties of LEDarrays and clusters can (and therefore should) be measured in the same way asclassical lamps. The TC should concentrate on quantities, effects or operatingconditions where LED arrays and clusters have peculiarities. These are: 1.Measurement of luminance. 2. Effects of heating/self-heating. 3. Chromaticity. 4.Amplitude modulation. The scope should include signs and static displays, whiledynamic displays are excluded. The TC member list will be reformed based onresponses from the participants. An email reflector will be set up for continuingdiscussions.(After the meeting, the TCC distributed the meeting notes with a new list of membersas shown above.)

He will start the finalofficial enquiry within TC2-52 on the photometry of emergency lighting at the end ofJune, after the London IEC 34 meetings. The concepts he promoted regarding

- 23 -

emergency ballast lumen factor are in a voting stage in IEC and as soon as approved,CIE can definitively publish the TC document. As he explained several times, IEC hasthe mandate to decide what to measure (the safety concept EBLF) and CIE shouldprovide recommendations on how to make the measurements. As he was working inboth bodies he could coordinate the two approaches.

transmittance measurement (CIE 130) to a joint ISO/CIE standardST: No report received.

R2-27 Field Measurement for Traffic SignalsReporter: C. Andersen (USA) AD: VandermeerschTR: To assess the need for a TC to produce recommendations on field measurements for

traffic signals, in particular those using LED arrays.ST: No report received.

R2-28 Evaluation of Colorimeter Spectral ResponsivityReporter: B. Kranicz (Hungary) AD: SauterTR: To review new methods for assessing the ‘quality-of-fit’ of the spectral responsivity of

colorimeters, particularly for use with new sources such as LEDs.ST: No report received.

R2-29 Characterization of Imaging Luminance Measurement DevicesReporter: P. Blattner (Switzerland) AD: SauterTR: To prepare a proposal for a new TC to prepare recommendations on the

characterization and calibration of CCD-based imaging photometers, having input fromD4 and D8 on the needs from the application side.

ST: Report given by Blattner with a PowerPoint presentation. The conclusions were:

- 25 -

- from a metrological point of view, Imaging Luminance Measurement Devices(ILMDs) are complex systems (traceability, software validation, etc),

- the parameters defined by CIE 69-1987 are not sufficient to characterize ILMDs,- there is interest from industry to have some guidelines on how characterize ILMDsThe reporter proposed a need for a new TC. Rattunde and Young supported the needfrom the manufacturers’ side. AD Johnson also supported. Proposed TR: Prepare aTechnical Report on methods for the characterization of imaging luminancemeasurement devices. Blattner finally agreed to chair this new TC.

R2-31 Problems with the Spectroradiometric Measurement of Light SourcesReporter: D. Gibbs (UK) AD: JohnsonTR: To consider the need for a revision of CIE 63 (1984) and make a recommendation

regarding whether a separate document is necessary to deal specifically with issuesrelating to band pass and sampling intervals, including the effects on color calculations.

ST: Gibbs proposed a new TC as below and volunteer to chair the new TC. Proposed Title:Effect of instrumental bandpass function and measurement interval on spectralquantities. Proposed TR: To produce a technical report that describes the effect ofinstrumental bandpass functions and measurement wavelength interval on spectrallyresolved quantities, and provide recommendations on suitable methods to minimise theerror introduced by instrumental bandpass functions on spectrally integrated orweighted quantities. It was suggested that the TC should also include recommendationson how to report data e.g. how should bandwidth and step interval be indicated in thedata file.

R2-32 Visual Appearance MeasurementReporter: M. Pointer (UK) AD: JohnsonTR: To monitor the work of Divison 1 on visual appearance measurement, which will

include potential new measurement areasST: AD Johnson reported, based on a written report received from Pointer. The work in D1

is in TC 1-65 Visual appearance measurement. A possible aim of "appearance"measurement is the development of a software tool that allows an evaluation of thevisual perception of a product based on physical measurements. Ultimately this couldlead to development of an instrument that can perform the tasks of a human observer inreal-time for a wide range of types of products and complex surfaces, evaluating colour,gloss, pattern, surface texture, etc. A copy of a National Physical Laboratory TechnicalReport (Measuring Visual Appearance – A Framework for the Future) has beencirculated to TC members for comment. The intention is that this report be published asa CIE Technical Report after a CIE NC ballot in late 2004. The first meeting of this TC1-65 was held as part of the CIE Division 1 meeting in Japan in June 2004.(See Attachment 2 for the full report by Pointer)

9. Proposals for dissolution of TCs and reporterships No TCs were proposed for closure.

Closure of the following reporterships was approved by vote with no objections.

R2-29 Characterization of imaging luminance measurement devices (Peter Blattner) … Anew TC will be established.

R2-30 Problems linked to correct measurement of TL5 fluorescent lamps with existingelectronic ballasts (Guy Vandermeersch) …. The work will be done in TC2-23.

- 28 -

R2-31 Problems with the spectroradiometric measurement of light sources (David Gibbs)… A new TC will be established.

A short report of these reporterships should be written for publication in CIE Collection.

10. Proposals for new TCs and reporterships

10.1 New Technical Committees

Establishment of the following TCs was approved by the Division with no objections:

TC2-59 Characterization of imaging luminance measurement devicesChair: P. Blattner (Switzerland) AD: SauterTR: To prepare a Technical Report on methods for the characterization of imaging

luminance measurement devices.This TC was proposed as a result of R2-29.

TC2-60 Effect of instrumental bandpass function and measurement interval on spectralquantities

Chair: D. Gibbs (UK) AD: SauterTR: To prepare a technical report that describes the effect of instrumental bandpass

functions and measurement wavelength interval on spectrally resolved quantitiesand provide recommendations on suitable methods to minimise the error introducedby instrumental bandpass functions on spectrally integrated or weighted quantities.

This TC was proposed as a result of R2-31.

10.2 New Reporterships

R2-35 Uncertainties in Distribution Temperature DeterminationReporter: Alan RobertsonTR: To investigate the potential effect of a change to the definition of distribution

temperature to include a statement regarding weighting the spectral distributionvalues by the uncertainty of the measurements at each wavelength.

This TC was proposed following the discussion of TC2-43 earlier in the meeting (see TC2-43 report above). D2 agreed to establish this reportership with no objection.

10.3 New Liaisons

No new liaison functions were established.

10.4 Changes in TCs and reporterships

The following changes in TCC were approved by the Division with no objection:The chair of TC2-16 changed from M.L. Rastello (Italy) to J. Schanda (Hungary)The chair of TC2-50 changed from G. Sauter (Germany) to J. Schuette (Germany)

11. General issues (DD Goodman)

11.1. Future D2 Symposia

- 29 -

Plans for future symposia were discussed last year and it was agreed at that time that theorder of priority was: 1) LED measurements, 2) uncertainty evaluation, 3) pulse sourcemeasurement. This list was reviewed and priorities of these topics for the next few yearswere discussed. Participants agreed that the next symposium should be on uncertainty. ADSauter suggested that it would be good to have it in 2006, when the TC2-43 document mayhave just been published. The requirement for a symposium on pulsed source measurementswas assessed as lower priority, due to relative lack of activity in this area, so should not bebefore 2007. The symposium on LED light sources just held was very successful andparticipants felt another such symposium on LED sources should be held in a few years,probably jointly with D1 and D6. Sauter suggested that next time there should be a strongerfocus on LED clusters as well as vision issues. Temporal aspects (modulation) should beincluded as well. D4 may also be interested. The timing can be 2006 or later, to be decidednext year.

It was suggested that symposia might be linked to publication sales: e.g., discount on otherpublications for symposium participants or inclusion of related publications as part ofsymposium materials.

Related to symposia, it was mentioned that a CIE Expert Symposium on Light and Health:The non-visual effects, coupled with a Tutorial: Light Measurement for Photobiology, willbe held in Vienna, Austria, on Sep. 30 - Oct. 2. The planned CIE Expert Symposium onImage Acquisition and Display, Sep. 15-17, Budapest, HUNGARY, has been cancelled.

Sauter suggested that traceability and MRA issues might also be a topic of a symposium orcould be included in the uncertainty symposium. DD answered that CIE BA is discussingsetting up a basic introductory course on the subject of light measurement. Traceabilityissues would fit this course well. It is possible that the course might be agreed and set up asearly as next year. Johnson suggested that optical properties of materials, especially oncomplex materials such as fluorescent materials, metallic and pearlescent materials, mightbe a good topic for a future symposium. This could be linked with work on ‘appearance’ inD1. DD will start a discussion on this possibility with D1 and will canvass general opinionsfrom D2 via the email reflector.

11.2. Future directions for measurement R&DIt is important that D2 is able to respond quickly to new measurement requirements, and DDwould therefore like to encourage people to think ahead about new and emergingtechnologies and possible new work needed for D2 in the near future. This should be kept asan item for discussion at each D2 meeting, and it was also suggested that a section should becreated on the D2 website to maintain a list of these topics. Last year topics discussed werelaser projection displays (a reportership was set up) and spectral measurement beyond the200 nm – 2.5 µm range (related to safety requirements). It was decided that it was still notnecessary to take any action on the latter, but it should be kept on the list. DD suggestedthat measurement of OLEDs might be important for the future. Gibbs mentioned smartpaper (reflectance can be controlled electronically), but it was thought this may be morerelated to D8. Young mentioned characterization of fiber optics as component ofmeasurement systems such as spectroradiometers (not for communication). Measurements

in the mesopic range might also become important if work in D1 to agree a system ofmeasurement is successful. These topics will all be added to the list for review next year. There was a question on any limit of number of TCs and reporterships. There are no ruleson this, but DD prefers not to open too many more TCs until some of the present ones havecompleted their work. Some discussion followed how the progress on TCs can be mademore rapid. Use of email and reflectors was strongly encouraged. Also there was a questionregarding whether there is any limit of number of members for a TC. Secretary pointed outa rule in CIE code of procedures that, when the TC document is published, only those whoactually contributed to the draft should be listed on the publication. So, even if many peopleare on the TC member list, not all of them need to be listed in the publication. 11.3. Database of optical radiation properties of sources, detectors and materialsDD Goodman reported last year that a database is being set up at NPL for the key opticalradiation properties of commonly used sources, detectors, and materials. The database isnow active and ready for people to upload data. The procedure is that the data should befrom either accredited laboratories or traceability to national standards is demonstrated. Ifnot, data can still be accepted but is marked untraceable. It will be open for people toupload and download data. It was proposed that a link to this database should be set upfrom the D2 website, and this was agreed. Links to other sites were also discussed, andparticipants agreed that links to key non-profit organizations would be useful. There aresome links already on D2 website, but the list is not complete. DD will ask everyone byemail about additional links to be added to make the list more complete. 12. Future D2 meetings:

2005It was agreed by unanimous vote that D2 will meet in Leon, Spain, in conjunction with CIEMidterm meeting and AIC meeting in May 2005. The meetings are already scheduled as:

May 12-14 CIE Board meeting and General AssemblyMay 16-17 CIE Divisional and TC meetingsMay 18-20 International Lighting Congress - Lighting in the XXI Century

2006There were two options: 1) an invitation from PTB, Braunschweig, Germany, where a newbuilding and new facilities such as a robotic goniophotometer have recently been set up.There will also be a conference “Interlumen” by German NC of CIE in conjunction. Timewill be May to June 2006. 2) ISCC will celebrate 75th anniversary of ISCC and CIEstandard observer, and there will be a symposium in Ottawa or Toronto in May 2006. D1decided to meet in conjunction with the symposium, and D2 and D8 are invited to makejoint meetings.

It was decided by majority vote (by all participants) that D2 will meet at PTB, Germany in2006. The symposium on uncertainty (see 11.1) will be connected to the D2 meeting.

R2-32 Visual Appearance MeasurementJune 2004

Established: San Diego, June 2003

Reporter: Mike Pointer GB

Approved Terms of ReferenceTo monitor the work of Division 1 on visual appearance measurement whichwill include potential new measurement areas.

The work in Division 1 is in TC 1-65 Visual appearance measurement.

IntroductionA possible aim of "appearance" measurement is the development of a software tool thatallows an evaluation of the visual perception of a product based on physical measurements.Ultimately this could lead to development of an instrument that can perform the tasks of ahuman observer in real-time for a wide range of types of products and complex surfaces,evaluating colour, gloss, pattern, surface texture, etc.

TC 1-65 will seek to establish the basic elements of a framework to aid the development ofa suitable measurement regime. It will require a review of existing techniques and theirsuitability to isolate the requirements for the development of mathematical and softwaretools to identify a key minimum set of measurands required, coupled with (and based on)real-time measurement of physical characteristics and visual assessments.

Suggested Work Programme1. To produce a technical report describing a suitable framework for the measurement

of visual appearance.2. To consider the establishment of separate Technical Committees to work on

specific aspects of visual appearance measurement, e.g. gloss, translucency.3. The whole question of terminology needs to be addressed – the present

International Lighting Vocabulary does not include many terms associated withappearance. We need to work with ASTM (ASTM Method E284 StandardTerminology of Appearance) to achieve harmony with CIE and get the necessaryterms into future editions of the ILV.

4. To produce a list of available instruments that could support the various elementsof the framework.

5. To produce a list of academic, and other research institutions that are working onaspects of the framework.

6. To consider the publication of case studies that show individual applications ofappearance measurement.

7. To encourage participation from industry in the work of refining the frameworkand building measurement procedures that relate to appearance.

ReportA copy of a National Physical Laboratory Technical Report (Measuring Visual Appearance– A Framework for the Future) has been circulated to TC members for comment. The

Liaison Report – ISO TC6/WG3

The most recent meeting of TC6/WG3 (paper, pulp and boards – optical properties) washeld in conjunction with the ISO TC6 meeting in Tokyo in November 2003.

The following agenda items are of possible interest to the CIE:

The liaison with the CIE:A report that I prepared of the CIE meeting in San Diego was discussed. The WG issatisfied that the CIE has agreed to retain the reference to the C-illuminant in the newColorimetry document (CIE Publication 15.3), in order to meet the needs of ISO/TC6. TheWG is also very interested in participating in the new CIE D1 Reportership on the need todefine an indoor daylight illuminant. WG members, A. Bristow and B. Jordan have alreadybeen in contact with the CIE Reporter, Dr. Janós Schanda, to inform him of the needs of thepaper industry. Dr. Byron Jordan (Canada) was appointed official liaison from ISO/WG3 toCIE.

Draft standards that have been recently submitted to member countries for ballot:ISO/CD 2469 – Determination of reflectance factor.

ISO/CD22891 – Determination of transmittanceIt was approved to change the terminology in sections 3.2 and 3.4 from “luminous

reflectance factor” to “luminance factor (illuminant/observer, C/2).

New work items:ISO/NP 20312. The determination of Colour under D50/2 conditions. The WG furtherapproved the suggestion that the wavelength range should be limited to the 400-700 nmrange in all future revisions of the optical standards, and that to avoid confusion the tables ofweighting factors should be truncated accordingly.
