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
![Page 5: 3D HOLOGRAPHIC PROJECTION](https://reader033.fdocuments.us/reader033/viewer/2022061420/555a78cbd8b42a98568b48c3/html5/thumbnails/5.jpg)
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
![Page 7: 3D HOLOGRAPHIC PROJECTION](https://reader033.fdocuments.us/reader033/viewer/2022061420/555a78cbd8b42a98568b48c3/html5/thumbnails/7.jpg)
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
![Page 8: 3D HOLOGRAPHIC PROJECTION](https://reader033.fdocuments.us/reader033/viewer/2022061420/555a78cbd8b42a98568b48c3/html5/thumbnails/8.jpg)
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
( Silver Halide Photographic Emulsion )

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

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
