Holography

Holography is a photographic technique that records the light scattered from an object and then presents it in a way that appears three-dimensional. This process involves the use of lasers to illuminate the subject and to record its image. Unlike traditional photography, which captures a two-dimensional image, holography captures the light field emitted by an object. This is achieved by recording the interference pattern between two light beams: the reference beam and the object beam, which reflects off the subject.
