INTRODUCTION TO HOLOGRAPHY

• Holography is composed of the Greek terms, "holos" for "whole

view" and “gram” for "writing or drawing“

• Technical term for holography is wave front reconstruction

• Image changes as the position and orientation of the viewing

system changes

• Records phase of the object

• Record our three dimensional world on a two dimensional

recording medium

INTRODUCTION TO HOLOGRAPHY(cont)

• Can be seen using naked eyes

• Demonstrates complete parallax and depth-of-field

• Image floats in free space

• Can also be used to optically store, retrieve, and process

information

HISTORY OF HOLOGRAPHY

• Dennis Gabor - discovered the basic technology

of holography in 1947

• Optical holography did not really advance until

the development of the laser in 1960

• First practical optical holograms that recorded

3D objects to be made in 1962

• Yuri Denisyuk from Soviet Union

• Emmett Leith and Juris Upatnicks from USA

• Advanced notably since the 1980s owing to low-cost

solid-state lasers

Dennis Gabor (1900-1979)

TIMELINE OF HOLOGRAPHY

WORKING OF HOLOGRAPHY

• Requires a laser as the light source

• Image is captured as interference

pattern

• Working of holography is divided

into two phases:

• Recording

• Reconstruction •Produce monochromatic light

COMPONENTS REQUIRED

• Laser • Usually helium-neon (HeNe) lasers are used

• Beam splitter• Device that uses mirrors and prisms to split laser beam into

two beams• Object beam • Reference beam

• Mirrors• Direct the beams of light to the correct locations

• Holographic film• Can record light at a very high resolution• Layer of light-sensitive compounds on a transparent surface

IMPORTANCE AND NEED OF 3D HOLOGRAPHIC PROJECTION

• Rapidly growing technology

• Project large-scale, high-resolution images onto free space

• Accommodate multiple viewers independently and

simultaneously

• Create tremendous effects on all fields of life including

business, education, science, art and healthcare

• Enabling viewing and manipulation of virtual 3D objects in 3D

space without the need for special viewing goggles or

headgear

EVOLUTION OF DISPLAYS

PROJECTED COST OF 3D HOLOGRAPHIC PROJECTION

WORKING OF 3D HOLOGRAPHIC PROJECTION

• Also known as ''Musion Eyeliner'‘

• Loosely based on an illusionary technique called Peppers Ghost

• John Henry Pepper - attempted to popularize the effect

A setup for Pepper's Ghost

WORKING OF 3D HOLOGRAPHIC PROJECTION(cont)

• Latest and vary unique Hi Definition 3D Projection Technology

• Image is captured in 3 dimensional Aspect with a Special Hi

Definition Camera on a specially built stage

• Projected at various Distant Locations

• Without wearing any kind of 3D glasses


• It starts with the

patented foil,

completely invisible to

the naked eye, right at

45° across the stage

• Holographic display is

based on a Spatial Light

Modulator A setup for Musion Eyeliner

DISPLAY SETUP

• A video projector, preferably DLP with an HD card/minimum native resolution of 1280 x 1024 and brightness of 5000+ lumens

• A hard-disc player with 1920 x 1080i HD graphics card, Apple or

PC video server, DVD player

• A Musion® Eyeliner™ Foil(1/8" thick Acrylic version) and a stage

set

• Lighting and audio as required

• Subjects are filmed in HDTV and broadcast on to the foil

through HDTV projection systems, driven by HD Mpeg2 digital

hard disc players, or uncompressed full HDTV video

WHAT WE COMPUTER ENGINEERS CAN DO IN THIS HOLOGRAPHY?

• Can describe all of the interactions between the object and

reference beams, as well as the shapes of the interference

fringes, using mathematical equations

• Makes it possible to program a computer to print a pattern

onto a holographic plate, creating a hologram of an object that

doesn’t actually exist

COMPUTER AND HOLOGRAPHY

COMPUTER AND HOLOGRAPHY(cont)

ADVANTAGES OF 3D HOLOGRAPHIC PROJECTION

• A high resolution three dimensional images

• Glasses free 3D display

• No need for projection screen

• Life like images

• Interactive display

APPLICATIONS OF 3D HOLOGRAPHIC PROJECTION

“Real world applications are endless”

• Live stage shows

• Advertising

• Gaming

• Education

• Entertainment

• Training

• Medical

• Communication

• Military and Space Applications

FUTURE SCOPE

Future IPad with an inbuilt Holographic projector

A palm sized holographic projector that projects an entire Computer. Your PC on

your palm!

FUTURE SCOPE(cont)

A teacher uses a holographic projection of the human

body to show body metabolisms

FUTURE SCOPE(cont)

CONCLUSION

• Holographic Technology has endless applications as far as

the human mind can imagine

• Will become a very integral part of human societies and

civilizations in the future

• In future, holographic displays will be replacing all

present displays in all sizes, from small phone screen to

large projectors
