holography technology for the future to lead in the market in the digital world. recent trends and it is attached with a video for good understanding. hope you will like the presentation

1. Holography

2. EVOLUTION OF DISPLAYS

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. • 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
INTRODUCTION TO HOLOGRAPHY (cont)

5. • 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
HISTORY OF HOLOGRAPHY

6. TIMELINE OF HOLOGRAPHY

7. • TIMELINE 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
WORKING OF HOLOGRAPHY
Produce monochromatic light

8. • 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 )
COMPONENTS REQUIRED

9. RECORDING A HOLOGRAM

10. A Hologram is the result of interference occurring between two
waves,
an object beam which is the light scattered off the object & a
coherent background,
the reference beam, which is the light scattered off the object & a
coherent background, the reference beam ,
which is the light reaching the photographic plate directly.

11. Holography is a
two-step
process.
First step is the
recording of
hologram
where the
object is
transformed
into a
photographic
record.
The second
step is the
reconstruction
in which the
hologram is
transformed
into the image.

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

15. PROJECTED COST OF 3D HOLOGRAPHIC PROJECTION

16. COMPUTER AND HOLOGRAPHY

17. • 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
WORKING OF 3D HOLOGRAPHIC PROJECTION

18. • 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
DISPLAY SETUP

19. • A high resolution three dimensional images
• Glasses free 3D display
• No need for projection screen
• Life like images
• Interactive display
