US Businessman Gregory Olsen Becomes Third Space Tourist The SBIR program provided the initial funding to allow Dr. Olsen to start Sensors Unlimited in 1991. The company was sold in 2000 for $700M to Finisar Corporation From: SBIR Program Diversity and Assessment challenges: Report of a Symposium Gregory Olsen answered first, saying that the SBIR had led him into intensive interaction with the university community. ÒI think thatÕs one of the great things about SBIR.Ó He said that he had often been asked for the names of people at a university to collaborate with. He had advised people not to Òforce it,Ó but simply to get to know the professor or student working on equipment or an area of common interest, and get to know them. ÒIÕm not sure thereÕs anything more you need to do.Ó David Goldston pursued this topic further, asking Dr. Olsen how SBIR helped to facilitate interactions with university people. ÒWas it just in having money that you could bring to a professorÕs project,Ó he asked, Òor did the program bring a Ôgood housekeeping seal of approvalÕ?Ó Gregory Olsen said it had been Òall of the above.Ó He had worked with Dr. Steven Forrest at Princeton University, whose field is optoelectronics. Dr. Forrest had arrived at Princeton around the same time Dr. Olsen started Sensors Unlimited. Dr. Forrest had equipment useful to both efforts, but no engineers to install it.

Goddard Flight Space Center - 1995 Phase II

Monolithic, Active Pixel InGaAs Near Infrared Focal Plane Array

Sensors Unlimited,Inc. Princeton, NJ

INNOVATIONDeveloped an InGaAs/InP active pixel sensor wherein monolithic circuit

functionality is integrated at every pixelInGaAs/InP Focal Plane Array

ACCOMPLISHMENTS• Technology incorporated into hybrid focal plane array (FPA) consisting of an InGaAs photodiode array operable in the 0.9 µm

to 1.7 µm spectrum at room temperature.• Contains a single stage thermoelectric cooler with an integrated thermistor allowing the user to reduce the temperature for

"high sensitivity" applications, such as low light level detection, or to stabilize the FPA in a varying ambient temperature. * Easy to operate because the clock drivers and analog gain are all on one chip.

COMMERCIALIZATION* Commercial sales of NIR imaging applications have exceeded $1 million for the past three years.• Imaging systems with 640 x 512 pixels on 25 µm pitch are currently available and 1280 x 1040 on 12.5 µm have been

demonstrated. Cameras with cut-off wavelengths beyond 2 µm have also been produced.•Technology used in many industrial and commercial applications such as night vision, fiber optics inspection, eye-safe

covert surveillance, spectroscopy, laser beam profiling, laser and light detection and ranging (Ladar, Lidar), machine vision,and many other applications where near infrared detection is required.

GOVERNMENT/SCIENCE APPLICATIONS•Technology was utilized in the LEISA Atmospheric Corrector (LAC) instrument, which was flown on NASA’s Earth Observing-1

(EO-1) mission. Rockwell Scientific Corporation built the LAC system and they report that the system is fully operational inmeasuring the spectral region that is sensitive to atmospheric variations.

NASA SBIR Contributions to the Deep Impact Mission

Scimeasure Analytical SystemsThe highest quality images from a ground observatory were made possible by wave front sensor cameras from Scimeasure Analytical Systems. These cameras are keyto the adaptive optics at the Palomar Observatory where astronomers continue to track the consequences of the impact on comet Tempel 1.

Barr AssociatesProvided optical filters for filter wheels and a dichroic beam splitter located in mission instruments on the flyby spacecraft. These instruments gathered images that will be used to analyze the results of the material ejected by the impact and the crater created by the impact.

High Resolution InstrumentComposite Optics Provided three telescope structures constructed from light weight, thermally stable composite materials. The structures were for the medium and high resolution imaging instruments on the flyby spacecraft and the telescope (not shown) on the impactor.Medium Resolution Instrument

General Aviation & NASA’s SBIR & STTR Programs

- The GA revitalization effort, embodied in the AGATE (Advanced General Aviation Transport Experiments) consortium, has strategically leveraged the SBIR and STTR programs to support its efforts.

- The AGATE program is a consortium of over 70 members from industry, universities, NASA, the Federal Aviation Administration, and other government agencies.

- AGATE’s goals are to help revitalize the ailing aviation industry by developing affordable new technologies and advocating new standards and certification methods for next-generation single-pilot, near all-weather, light aircraft.

Photodynamic Therapy

INNOVATION

Using technology derived for NASA’s Space Shuttle plant growth experiments, tiny,pinhead-sized light-emitting diodes (LEDs)have been developed for cancer treatment and wound healing.

ACCOMPLISHMENTS

• In its work in cancer treatment, Quantum Devices of Barnveld, Wisconsin, uses its LEDprobe to activate photosensitizers - light sensitive, tumor treating drugs. The LED activation process allows the drugs to destroy cancerous cells and leave the surrounding, healthy tissue virtually untouched.

• The surgical probe may also emit longer waves of red light to stimulate a new drug called Benzoporphyrin Derivative (BPD). Surgery with the improved probe and medicine are very promising.
