2. Holography:
Holography is the process of making holograms, which are three-
dimensional images. A hologram may also project a three-
dimensional image into air.

3.  Hologram is a scattered image that is interaction of two beam lasers .
 The word hologram comes from the Greek words holo means whole
and gram means message.
 Whole message means 3-D image.
Hologram:
The Transmission Hologram:
 The laser is split to form an object beam and a reference beam.
 The light from the illuminated object and the reference beam form
an interference pattern on the film.
 This pattern (hologram) contains the information about the object
which can then be viewed as a three dimensional image.

4. History of Holography:
Dennis Gabor
 Holographic Technology Invented in 1948 by
Dennis Gabor for use in electron microscopy,
before the invention of the laser.
 Dennis Gabor is considered the Father of
Holography and Holographic Technologies.
 Leith and Upatnieks (1962) applied laser light
to holography and introduced an important
off-axis technique

5. Touchable Holography:
 Researchers from The Tokyo University have Invented a touchable
hologram in 2009.
 The display to track hand motion, and an airborne ultrasound tactile
display created in the university's lab to create the sensation of touch.

6. Holographic Computers:
 Holographic computers is the method of digitally generating
holographic interference patterns.
 3-D holographic computer, a product that isn't on the market yet.
But I think it will be someday soon.
 Sony designer Hiromi Kiriki has devised some sleek concepts for
wearable computing devices

7. Holographic data storage:
700 MB 9 GB 30~50 GB
What is next ?

8. • It is estimated that until now people have produced more than 5 exabytes
(5 billion gigabytes).
• While HVD is attempting to revolutionize data storage, other discs are
trying to improve upon current systems.
• HVD products need to be very cheap in order to compare with DVD drives

9. Holographic security:
Hologram Authentication :
 Identity card
 Passport.
 Sticker or Tag.

10. Passport.
Sticker or Tag.

11. Why hologram for Authentication:
 Hologram stickers cannot be scanned or photocopied .
 Hologram stickers can also create a unique and attractive complement
to your existing packaging and product.
 Protect your product from potential counterfeiters with this highly
sophisticated tamper evident security hologram.

14.  Holographic Technology and Spectral Imagining has endless applications,
as far as the human mind can imagine.
 Holographic Technology is most advanced technology.
 These technologies are indeed available and getting more robust in
abilities each year.
 Holographic Technologies are not just about art or business
communication, they are about safety, security, education, planning and
the strength of our civilization
