Holography is, the science of recording interference pattern of light in space usually specific to a object. Hologram can be viewed by illuminating by shining a light at a specific angle, when the light waves will be recreated and the viewer perceives the original object as it is really there!

Hologram is the result of recording interference patterns of light on a photo - sensitive plate. A light beam generated by a single laser is used to make the hologram, The laser beam is used to illuminate both the object to be recorded and the light-sensitive plate. One half of the beam, called the reference beam is cast directly onto the light (photo) - sensitive recording plate. The second half, known as the object beam is shone onto the object to be recorded. The light reflected from the object strikes the recording plate, causing an interference pattern specific to the object being recorded. The exposed plate is developed in a similar manner to that employed for photographic process. The hologram is replayed by illuminating the developed plate with a beam identical to the reference beam. When viewing the hologram, one sees a three dimensional image of the recorded object.

The holographic film records an infinite number of views of the object, whereas a photograph records only one view. Thus, when viewing a hologram, the left eye sees a different set of information than the right eye so that the image appears three dimensional.

Yes. Specially filmed motion pictures of 3 to 10 second lengths can be used to create animated holographic images. This process is known as stereogram and the resultant image can be viewed under tungsten light point source.

Other than stereogram holography which is created on computer from movie footage, most holographic formats reproduce the identical size of the original object. These reproduced images cannot then be reduced or enlarged.

In fact holograms became economical when mass produced and the most cost effective method is the embossed hologram process. This is produced in polyester film paper and many other substrate all having the same spectral quality to the image.

Yes - A hologram can be made from flat art but it will not add depth which was not originally there, similarly photographs reproduced in a hologram will only show what is in the photograph. The holographic process cannot add depth to a photograph.

Yes. True-color holograms can be made.
