Holography

Holography is the science and practice of making holograms. This is commonly used in a varety of applications ranging from data storage to artistic expression. A hologram is a real world recording of an interference pattern which uses diffraction to reproduce a 3D light field rather than an image formed by a lens, resulting in an image which still has the depth, parallax, and other properties of the original scene.
== Applications ==
Holography has many civilian uses within UEG space. For example, many nightclubs make extensive use of holographic wall, ceiling, and floor panels for decorative purposes. Holographic tape is used to display information and images on the sides of civilian vehicles. Security holograms are also incorporated into personal identification cards and credit cards in order to prevent forgery. Holographic scanners are used in post offices, shipping firms, and automated conveyor systems to determine the three-dimensional size of a package. They are used in tandem with checkweighers to allow automated pre-packing of given volumes for bulk shipment.
