This document provides an overview of holography, including its definition, history, principles, recording and reconstruction processes, properties, and applications. Holography allows for the recording and reconstruction of three-dimensional images of objects using the properties of light. The technique was first proposed by Dennis Gabor and later developed by Leith and Upatnieks using lasers. Current and future applications of holography include advertisements, medical imaging, entertainment, and architecture. The technology continues to advance and may eventually replace other display methods.

4. 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.

6. 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.

7. Principle of Holography
Holography is two way process :1. Recording of the hologram
2. Reconstruction of the hologram

8. Recording of the Hologram

9. Reconstruction of the Hologram

10. 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.

11. Current and Future Applications
Advertisements
Medical Science
Entertainment
Architecture

12. 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.

14. Entertainment
Holograms are used in movies to show virtual
images.
Architecture
 Use of holography in architecture is recording
of models and previsualise new buildings.

16. 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.
