This document discusses 3D holographic projection technology. It begins with an introduction to holography, including its history and how it works. The document then discusses the importance and workings of 3D holographic projection specifically. Some key advantages are that it allows for glasses-free 3D displays without the need for a projection screen. The document outlines various applications such as live shows, advertising, education and more. It concludes by discussing the future potential of the technology and how holographic displays may replace current screens.

3. 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
4. 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
5. 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)
7. 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
8. 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 )
14. 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
17. 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
18. 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
19. WORKING OF 3D HOLOGRAPHIC
PROJECTION(cont)
• 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
21. 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
22. 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
25. ADVANTAGES OF 3D HOLOGRAPHIC
