Sapan in 1982. Jason Sapan, also known as Dr. Laser [1] (pronounced Sāpăn; born 1950) is a holographer and actor who is the founder of Holographic Studios, the world's oldest gallery of holography, located in the borough of Manhattan in New York City.
The hologram keeps the information on the amplitude and phase of the field. Several holograms may keep information about the same distribution of light, emitted to various directions. The numerical analysis of such holograms allows one to emulate large numerical aperture, which, in turn, enables enhancement of the resolution of optical microscopy.
Computer-generated holography (CGH) is a technique that uses computer algorithms to generate holograms.It involves generating holographic interference patterns.A computer-generated hologram can be displayed on a dynamic holographic display, or it can be printed onto a mask or film using lithography.

Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE. "Say" for EG, used to mean "for example". More obscure clue words of this variety include: "Model" for T, referring to the Model T.
The rainbow hologram (also known as Benton hologram) is a type of hologram that was invented in 1968 by Dr. Stephen A. Benton at Polaroid Corporation (later MIT). [1] Rainbow holograms are designed to be viewed under white light illumination, rather than laser light which was required before this.

The hologram is made by measuring acoustic pressure away from the source using an array of transducers (microphones) or a single scanning transducer. The next stage is data processing with a computer. Fourier transforms are used to convert information from the time domain into the frequency domain. A set of intermediate holograms are produced ...
