Entity: HOLOGRAM
A hologram is a three-dimensional image reproduced from a pattern of interference produced by a split coherent beam of radiation, such as a laser. It is a technology that creates the illusion of depth and dimensionality.
HOLOGRAM
Etymology
The term 'hologram' is derived from the Greek words 'holos' meaning whole and 'gramma' meaning message or record.
Definition
A hologram is a three-dimensional image or photograph that appears to be solid and has depth, created using laser technology. It is produced from a pattern of interference generated by a split coherent beam of radiation, such as a laser.
Historical Context
The concept of holography was first developed by Hungarian-British physicist Dennis Gabor in 1947. The technology has since evolved and found applications in various fields including art, security, and entertainment.
Cultural Significance
Holograms have become iconic in popular culture, often depicted as futuristic or magical. They are used in art installations, performances, and even as security features on credit cards and IDs.
