Technology and Holography

 Watching movies in the third dimension
might seem like space-age entertainment,
but the technology is older than your great
grand father.
 According to sensio, a Canada-based
manufacturer of 3D home Technology
“Stereoscopic photography, or the technique
of creating a ‘Third dimension’ was first
invented in 1838”.

 3D technology stands for three-dimensional
technology.
 3D technology is the illusion of depth, it is a
visual representation system that tries to
create or reproduce moving objects in the
third dimension,
 In simple that we have feel that whatever
happens in 3D effect it is part of our real life.

 The process by which we turn an image in 3D
is known as stereoscopic photography.
 Stereoscopic photography is that in
which two photographs taken from slightly
different angles that appear three-
dimensional when viewed together.

 We can see 3D images by help of 3D glasses
which are specially manufactured for viewing
3D images. There are two types of 3D glasses
which are
 Anaglyph 3D glasses
 Polarized 3D glasses
 Pulfrich 3D glasses

 These glasses consist on two different colors of
lenses which are red/blue. These glasses are used in
viewing 3D comics, 3D movies, 3D TV, 3D gaming
and 3D art.

 More modern choice for cheap 3D.
 They work kind of the same way as the red/blue glasses
though, but at different polarizations.
 The corresponding glasses would allow horizontal polarization
in one eye and vertical polarization in the other.

 Another type of 3D glass which is used to view 3D
image. These mostly used in 3D laser show, 3D ride
simulators, 3D multimedia displays etc.

 Pulfrich viewing technique is that images seen
through the clear lens reaches the brain slightly
faster than images seen through the dark lens. With
properly sequenced movement recorded on film or
video, objects moving across the horizontal field of
vision create the illusion of 3D. The pulfrich method
of 3D is used in viewing TV, video and 3D computer
display.

STRENGTHS
•Unique experience (realistic feel)
•Companies producing 3D flat displays
are well-known in the industry such as
Sony and Toshiba
•Partnerships – with movie industry
•Wide coverage of technology
•Wide array of R&D teams
WEAKNESSES
•Costly
•Slow development of underlying
technology
OPPORTUNITIES
•Technology on the rise
•Technology trigger (booming)
•Improving economy
•Industry competition
•Publicity
THREATS
•Leakage of critical information
•Piracy of employees
•Fast-phased technological environment –
can be easily phased out

 It is no secret that students of today live in a
multimedia world where They use video as their
primary form of engagement and communication.
 Teachers and administrators are looking for ways
to present information to student that will not only
spark there interest but also encourage them to
explore a subject more thoroughly.
 The advent of affordable 3D technology promises
to bring in to reality the Dream of fully engaged
students.

 In making 3D films…
 Likes Raone, Avatar, Don 2..
 Making 3D display of television..
 Making 3D games
 Call of Duty
 Dead Rising
 Bat man

INTRODUCTION TO HOLOGRAPHY
• Holography is composed of the Greek terms, "holos" for "whole
view" and “gram” for "writing or drawing“
• It is an advanced form of photography that allows an image to be recorded in
three dimensions.
• The technique of holography can also be used to optically store, retrieve, and
process information.
• Image changes as the position and orientation of the viewing
system changes.
• Record our three dimensional world on a two dimensional
recording medium

HISTORY OF HOLOGRAPHY
• Dennis Gabor - discovered the basic technology
holography in 1947
• Dennis wrote a paper in 1948
that has become the foundation
of modern Holography.
• The most interesting thing about
all this is that laser light had not
even been invented yet, when he wrote his paper
Dennis Gabor
(1900-1979)

 If you look at these holograms from different
angles, you see objects from different
perspectives, just like you would if you were
looking at a real object
 They usually just look like sparkly pictures or
smears of color
 If you cut one in half, each half contains whole
views of the entire holographic image

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

 Identity card.
 Passport.
 Sticker or Tag.

 Hologram stickers cannot be scanned or
photocopied .
 Hologram stickers can also create a unique
and attractive complement to your existing
packaging and product.
38

 Holography is a high resolution three dimensional
recording of an object from a limited perspective.
 Security: Holograms are widely used for security
purpose.
 It is not possible to duplicate Holograms
 Holograms are quick and easy optical validation.
39

 Hard to see without good direct point source of
light.
 Not that bright.
 Not visible in dark.

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
