Introduction
Holography is the science and practice
of making holograms and Hologram is a
three-dimensional imaging technique. In
fact, the term "hologram" was comes from
the Greek words holos, meaning "whole,"
and gramma, meaning "message." A
hologram creates everything your eyes
see -- depth, size, shape, texture, and
relative position from many points of view.

Virtual Reality is a computer
generated, multi-sensory information
program which tracks a user in real
time i.e. computer system is used to
create an artificial world in which the
user has the impression of being in
that world, with the ability to navigate
through and manipulate objects in
that world.

2. 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 (now Russia).
• Emmett Leith and Juris Upatnicks from USA.
 Advanced notably since the 1980s owing to
low-cost solid-state lasers.

3. History of Virtual Reality (VR)
The first references to the concept of
virtual reality came from science
fiction. Stanley G. Weinbaum's 1935
short story "Pygmalion's Spectacles"
describes a goggle-based virtual
reality system with holographic
recording of fictional experiences,
including smell and touch.

Spectacles science fiction.

 In 1930s, flight simulators were built
by US Air Force to train student pilots.
 In 1965, a research program for
computer graphics called “The
Ultimate Display” was laid out.
 In 1988, commercial development of
VR began.
 In 1991, first commercial
entertainment VR system "Virtuality"
was released.
 The Sensorama was released in the
1950s.

4. Techniques behind Holography
Fig: Basic construction of a Reflection Hologram.
A LASER beam make two
beam by half mirror.
Another two mirror construct
the Hologram of the object.
Generally Red and Green
colour LASER beam used.

5. Techniques behind Virtual
Reality (VR)
 Lens  Tracking Technology Display  3D Audio
Head Mounted Device (HMD):

 The data gloves are take
the sense of moving arm.
 When user moves his/her
arms then user feel the
real arms move in virtual
system.
 Also data gloves track
the sense.

6. Comparison between Holography and Virtual
Reality (VR)
 Holography is a technique which enables three-
dimensional images (holograms) to be made.
 VR is a computer-simulated environment that can
simulate physical presence in places in the real world or
imagined worlds.
 It involves the use of a laser, interference,
diffraction, light intensity recording and suitable
illumination of the recording.
 It involves the use of VR software and mobile device.
 Holography can only create visual experiences.  Virtual reality can recreate sensory experiences, which
include virtual taste, sight, smell, sound, touch, etc.

Conclusion Holographic Technology has endless applications as far as
the human mind can imagine.
 In future, holographic displays will be replacing all present
displays in all sizes, from small phone screen to large projectors.
 Though the disadvantages of Virtual Reality can disturb the humans perception ability, its advantages
in different fields makes it user friendly.
 The sole objective of virtual reality is to give the user an environment as realistic as possible and a
thrilling sensory experience.
 The technology of virtual reality is advancing rapidly and it won't be long before it becomes a most
exciting source of entertainment in our homes.
