There are also cylindrical 360° floating images, multiple image holograms that change as you walk by, and computer generated holograms as well as a selection of novelty hologram items and stickers. Directly below the gallery is the laser laboratory where holograms are created. [ 4 ]
There are three important properties of a hologram which are defined in this section. A given hologram will have one or other of each of these three properties, e.g. an amplitude modulated, thin, transmission hologram, or a phase modulated, volume, reflection hologram.
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.
Zebra Imaging was a company that developed 3D digital holographic images, hologram imagers and interactive 3D displays for government [1] and commercial uses. The company offers digital holograms that are autostereoscopic (no glasses or goggles required), full-parallax (viewing of the image from viewpoints above and below as well as from side to side) and in monochrome or full-color.
8i was founded in May 2014 [1] by Linc Gasking, Eugene d'Eon, Sebastian Marino and Joshua Feast [2] to develop software that can capture, analyze, compress, and recreate all the viewpoints required for volumetric capture.
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.

Holography is the science of producing holograms; it is an advanced form of photography that allows an image to be recorded in three dimensions. Subcategories This category has the following 4 subcategories, out of 4 total.
[1] [2] The essence of the DPH technology is embedding computer designed digital holograms inside a planar waveguide. Light propagates through the plane of the hologram instead of perpendicularly, allowing for a long interaction path. Benefits of a long interaction path have long been used by volume or thick holograms. Planar configuration of ...
