Hologram: meaning, definitions and examples

visual representation

A hologram is a three-dimensional image created by the interference of light beams from a laser or other coherent light source. Unlike traditional photographs, holograms can display images with depth and parallax, allowing viewers to see different perspectives as they move. They are used in a variety of applications including data storage, security features on credit cards, and artistic displays. Holography, the technique used to create holograms, captures the light scattered from an object and records it to form a holographic image.
