Hisense's Giant 136-inch TV. Hisense is the frontrunner in the massive TV for consumers space race. Last year, I reviewed the larger than life 110 inch QLED, and it was remarkable.Now, it's ...
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.

Embossed holograms are used widely on credit cards, banknotes, and high value products for authentication purposes. [3] It is possible to print holograms directly into steel using a sheet explosive charge to create the required surface relief. [15] The Royal Canadian Mint produces holographic gold and silver coinage through a complex stamping ...
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.
[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 ...

When the electrons in copper interact with the carbon monoxide molecules, they create interference patterns that create an electronic quantum hologram. This hologram can be read like a stack of pages in a book, [ 3 ] and can contain multiple images at different wavelengths .
