Computer generated hologram looks like a binary representation of an interoferogram. Computer generation is a means for producing hologram. Computers can be used to scan, enhance and create images and patterns for developing stereograms, as well as 2D and 2D/3D holograms. Often these images cannot exist in the real world.

To make a computer generated hologram first a image is taken of an object. The image background is then removed and whitespace added around the object to obtain higher transmission.
