What is Holography
 Holography (from the Greek, whole + write) is the science of producing
holograms.

 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.

 Holography is a technique that allows the light scattered from an object to be
recorded and later reconstructed.
History of Holography
 The principle of Holography was put forward by Dennis Gabor
for use in electron microscope ,before the invention of the laser.
 Dennis Gabor is considered the Father of Holography and
Holographic Technologies.
 Leith and Upatnieks revised Gabor’s idea in photography &
Now this technique is known as holography.

Principle of Holography
Holography is two way process :1. Recording of the hologram
2. Reconstruction of the hologram
Recording of the Hologram
Reconstruction of the Hologram
Holographic Properties
 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 .
 It provides image intensity that we can zoom ,rotate ,manipulate the image.
 If you cut one in half, each half contains whole views

of the entire holographic image.
Current and Future Applications
Advertisements
Medical Science
Entertainment
Architecture
Advertisements
Holograms are used in advertisements and consumer
packaging of products to attract potential buyers.

Medical Science
 Use of holography in medical science overcome
the greatest challenges.
Entertainment
Holograms are used in movies to show virtual
images.

Architecture
 Use of holography in architecture is recording
of models and previsualise new buildings.
Conclusion
 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.
 In future, holographic displays will be replacing all present displays in all sizes,
from small phone screen to large projectors.
Thank You !!
