Principel holography

What’s holography?
Holography is the process or technique of making holograms, which are three-dimensional images. A hologram is produced by the interaction of two beams of laser light (light composed all of the same color, or wavelength), which have been split from a single beam by a mirror.
Principle of Holography
Holographic Principle is about encoding information from (D+1)-dimensional space onto D-dimensional space. It can be the interference pattern on a photographic plate from a three-dimensional object, or the entropy impressed on the surface of a black hole, or a physical theory translated into another form. Such principle is now embraced by some physicists, who claim that it will become part of the foundations of new physics, from which quantum theory and relativity may both deduced as special cases. The followings will explored the above-mentioned examples in more detail.
The Transmission Hologram
The coherent light from 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.
