hologram
Laser-made illusion
A hologram is a three-dimensional image created by recording light patterns on a photographic medium, producing an illusion of depth that shifts as the viewer moves.
Unlike flat photographs, holograms capture spatial information, making the image appear to float in space.
Security holograms on credit cards and currency are familiar examples, designed to be difficult to counterfeit.
In science fiction, hologram often refers to any projected 3D image, whether or not it uses actual holographic technology.
