Holography is a 3D imaging technique that uses lasers to record light patterns from an object and recreate its dimensions and depth when viewed from different angles. It can render subjects with complete dimensional fidelity, appearing so real that viewers want to touch them. Recent advances in holographic technology allow for projecting lifelike 3D moving images of people for presentations, entertainment, and virtual meetings without needing to travel. However, fully realizing the potential of holographic communication will require more advanced computers and internet infrastructure.

4. Now a days we have so many techniques for tele communication to
communicate with others. That are telephone, tele conference(video
conference),tele immersion, virtual reality,3D-halography.And also we have
a technique named by tele portation. But tele portation needs most
advanced technology like quantum computers and e tc.
In those tele phone is widely used technique. Tele conference is used
by the higher authority of officers. Tele immersion, virtual reality is going to
be used in special cases.
But the three- dimensional holography is separate from all of the
above techniques. Using this advanced technology we con see any person or
thing in front of us in our room, using high definition holographic projector.

5. Unlike photography or painting, holography can render a subject with complete
dimensional fidelity. A hologram creates everything your eyes see -- depth, size, shape,
texture, and relative position – from many points of view. In fact, the term "hologram"
was coined from the Greek words holos, meaning "whole," and gramma, meaning
"message."
Holography is a three-dimensional imaging technique. It uses laser light to record
the patterns of light waves reflected from an object onto the emulsion of light
sensitive film (or glass plates). When that film is developed, and re-exposed to laser
light (or normal incandescent light like most holograms today), it re-creates -- in space
-- all the points of light that originally came from the object. The resulting image,
either behind or in front of the holographic film, has all the dimensions of the original
object and looks so real that you are tempted to reach out and touch it -- only to find
nothing there but focused light.

6. “Mujan I liner system” is a new technology. It will projects
moments and image of a person where we want to place.
Through this technology an image generates a transference
screen and it will appears as three- dimensional image by
setting that are exit in the backside of transference screen.
Now there is no need to journey from one place to another
place. By using this technology we will give the live
presentation where ever from this place. We can use this
technology in education, entertainment, media, business etc. It
will available within four years in the market. It will have done
only one person in different to appear on live.

8. A unique presentation system that projects moving, 3-dimensional
images of people onto a small theatrical stage that is set with real objects,
artifacts, or client products. A 6-12 minute show-stopping theatrical
production.
Spectral Imagery is a presentation
system that can project a 3-dimensional
image of your company's spokesperson
-- real or fictional -- in thin air onto a
small stage set with props or real life
objects. From that vantage point, this
magical illusion can walk around and
tell your story to fascinated audiences.

9. Specially prepared video images that
are projected onto transparent screens of
glass or Plexiglas to achieve holography-like
special effects. Logos and products can
appear to move and float in space.

10. Special-commission large-format holograms for use in trade shows & conventions, and
corporate lobby displays. Mind-boggling images jump off the film as viewers try to touch
them, only to find nothing there but focused light.
Custom-image holograms help to meet the
corporate marketing objectives of our
clients. We work closely with our clients to
design and develop imagery that is
memorable, with high visual impact. The
applications range from holograms used to
attract customers and prospect at trade
shows to mass produced images included in
publications and specialty advertising
products

11. The 3D interference pattern of light scattered by an object and a
reference laser beam can be etched volumetrically. In brighter
regions of the interference pattern, mobile charge carriers —
electrons (-) and 'holes' (+) left by departed electrons — are
generated and the more mobile holes drift into the darker regions.

12. There are several hurdles that have
been holding holographic storage
back from the realm of mass
consumption, including price and
complexity. Until now, the systems
have required a cost-prohibitive level
of precision in manufacturing. But
recent changes have made the
holographic versatile disc (HVD)
developed by Optware a viable
option for consumers.

13. 1. 3-D hologram is most useful in business applications.
2. It gives the best results military uses like aircraft wings.
3. The use of holograms to locate and retrieve information without
knowing its address in a storage medium, but by knowing some of
its content.
4. The Air Force Scientific Research Office has taken the wraps off a
research project that uses holography to create high-definition, 3-D
images.
5. Supermarket scanners read the bar codes on merchandise for the
store's computer by using a holographic lens system to direct laser
light onto the product labels during checkout.
6. Imagine being able to record 100 movies on a disk the size of a CD - or one day recording the contents of the Library of Congress on such
a disk. These are the promises of holographic data storage.

14. 1.Through this technology the pop singer Madonna has danced in gramee awards
without her involvement. That means the life size hologram of Madonna was
presented in gramee awards.

17. 1.In world football awards programme (fifa) a player named
by Mister Woo was appeared as three persons at a unique
time.
2.First time in the world the fashion show without models
was done in Newyork in this fashion show the dresses of
male and female were only cat walked by the holo magic.
3.In a press meet the football player David Beckhom was
appeared in holo form to expose the details of “London
Olympics 2012”.

18. The holography rapidly changes our daily lives. With this
technology there is no need to phone call. Simply we call a
particular person and invite to the virtual room And we can talk
with him as direct. More number of people will be interactive
with one another in an small conference hall.
Even it give the this type of advantages, we don’t have the
perfect PC’s which full fill the requirements of this technology ,
and also it needs INTERNET2(WWW2).
