NEW CONCEPT OF HOLOGRAM

Hologram, three dimensional images, which actually looks like real object. Basically, in photography it is not possible. Holography is all about storage of image including intensity and phase difference of all points of object and further formatting it in accordance with its record.

But conclusively what we have learned is insufficient. We have studied the theory but haven’t ever thought do it practically. The problem is that reconstruction of image seems non-feasible because in order to view 3D image the ray has to stop propagating at some distance. In the similar way all the rays from object or source must form a plane in space. Here arise a problem that how can ray be stopped traveling at some distance. What if all of sudden medium changes while propagation of light? If it happens then some light refracts while some reflects and we will be able to watch where the light has reflect. If now bulk of rays together bend then we will be able to see line, plane and even object.

We have seen concept of how to discover an image but how medium can be possibly changed. Here is the solution. The path through which the light propagate, from its lateral side, beam of radiation is sent from transmitter to receiver, which is on the opposite side parallel to it. Due to the radiation, the property of air interferes and thus light may divert from original path.  The figure below makes it clear.

AO=ray of light from source

BO=reflected ray

XO=refracted or absorbed ray

At ‘O’ ray of light can be seen distinctly. For a ray of light, a point, for a beam and a bulk of light, object can be discovered.
