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.

The purpose of Holus is to simulate holographic experiences and is technically different from typical hologram stickers found on credit cards and currency notes. Holus has been criticized by some commentators as a revamping Pepper's ghost, a 19th-century optical trick. [1] [2]
A typical game station consists of a hologram generator, usually placed in the cylindrical base of the set, on which there is a board made of three circles filled with alternating white and black fields. When launched, colorful, three-dimensional characters are generated.
Time Traveler or Hologram Time Traveler is a LaserDisc interactive movie arcade game.It was designed by Dragon's Lair creator Rick Dyer, and released in 1991 by Sega.Its plot is that an American old west cowboy named Marshal Gram travels to various timelines to rescue Princess Kyi-La and defeat the evil time lord Vulcor.

When the hologram plate is illuminated by a laser beam identical to the reference beam which was used to record the hologram, an exact reconstruction of the original object wavefront is obtained. An imaging system (an eye or a camera) located in the reconstructed beam 'sees' exactly the same scene as it would have done when viewing the original.
Since its introduction, vibrometry by holographic interferometry has become commonplace. Powell and Stetson have shown that the fringes of the time-averaged hologram of a vibrating object correspond to the zeros of the Bessel function (), where (,) is the modulation depth of the phase modulation of the optical field at , on the object.

Unlike conventional wavefront holograms, specular holograms do not depend on wave optics, photographic media, or lasers. The principle of operation is purely one of geometric optics: A point light source produces a glint on a curved specular (shiny) surface; this glint appears to travel on the surface as the eye or light source moves.
