Holoprojector

A holoprojector—also known as a holo-projector, holojector, hologram projector, holograph projector, holoproj, and 'proj—was a device that could record, transmit and receive hologram images. Traditionally, these images were used for communication, but some holoprojectors, known as holo-emitters, were also designed as tools for entertainment and academic purposes. Most astromech droids were outfitted with a holoprojector.

Holoprojectors projected an organized arrangement of light to create a 3-D replica of the subject. These holograms were used for communication, information displays, and entertainment. Most holoprojectors were equipped with sound so that the user could hear the subject talk in perfect sync.
