Holographic Projector

A holographic projector (or holographic emitter) is a device used to create holograms. They do this by manipulating photons and force fields to create a realistic, but virtual image. This technology is used in the recreation, labour and medical fields.

A rapid rise in the use of holographic projectors occurred in the late 24th century. In 2364, they were only installed in specialized rooms onboard Federation starships called holodecks. When the USS Voyager was commissioned in 2371, holographic projectors were installed in ship's sickbay as well. This was in order to allow the use of the Emergency Medical Hologram.
