  4. 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.
  5. 5. 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. Dennis Gabor 6
  6. 6. Principle of Holography Holography is two way process :1. Recording of the hologram 2. Reconstruction of the hologram
  7. 7. Recording of the Hologram
  8. 8. Reconstruction of the Hologram
  9. 9. 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.
  10. 10. Current and Future Applications Advertisements Medical Science Entertainment Architecture
  11. 11. 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.
  12. 12. Entertainment Holograms are used in movies to show virtual images. Architecture  Use of holography in architecture is recording of models and previsualise new buildings.
  13. 13. 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.
