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.
By 1971, Cross had made his way to San Francisco, California and founded the San Francisco Holography School, to teach his hologram techniques, setting up a studio in the basement of Project One. [3] In 1972, he developed the "integral hologram" by combining holography with conventional cinematography to produce three-dimensional images that ...
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.

Las Vegas, NV, Jan. 08, 2025 (GLOBE NEWSWIRE) -- Proto Inc. announced today at CES, the launch of the Proto M2 Foundation Series, the newest desktop hologram and spatial compute device. Proto is the original inventor of hologram machines and the platform that makes holoportation and AI-powered spatial compute possible.
Since then, his holograms have been exhibited regularly in France and abroad. From 1995, he developed a new process, called Ultimate, [6] which made it possible to record colour holograms using three lasers (red, blue and green) instead of the traditional process, which only used a red laser. The originality of this technique lies in the ...

Ordinary holograms are three-dimensional images encoded in a two-dimensional surface, such as the hologram on a typical credit card. "This time, the entire universe is encoded," he said.
Electron holography is holography with electron matter waves.It was invented by Dennis Gabor in 1948 when he tried to improve image resolution in electron microscope. [1] The first attempts to perform holography with electron waves were made by Haine and Mulvey in 1952; [2] they recorded holograms of zinc oxide crystals with 60 keV electrons, demonstrating reconstructions with approximately 1 ...
