The Hologram is based upon Nobel Prize winner Dennis Gabor's theory concerning
interference patterns. Gabor theorized in 1947 that each crest of the wave pattern
contains the whole information of its original source, and that this information
could be stored on film and reproduced. This is why it is called a Hologram.
Holography is the only visual recording and playback process that can record
our three-dimensional world on a two-dimensional recording medium and playback
the original object or scene, to the unaided eyes, as a three dimensional image.
The image demonstrates complete parallax and depth-of-field. The image floats
in space either behind, in front of, or straddling the recording medium.
