HOLOGRAMME Meaning and
Definition
-
A hologramme is a three-dimensional image produced by a holographic technique, which utilizes interference patterns to capture and display the light waves reflecting off an object or scene. A hologramme is created by splitting a laser beam into two identical beams: the object beam and the reference beam. The object beam is directed towards the object or scene being recorded and reflects or scatters off the surface. The reference beam is directed onto a photographic film or plate without any exposure to the object. When the two beams meet at the film or plate, they interfere with each other, creating an intricate pattern of light and dark areas that form the holographic recording.
When this recorded holographic plate is subsequently illuminated by a laser beam, the diffraction patterns on the plate cause the re-emergence of the original wavefront, reconstructing the full-depth holographic image. This creates the illusion of a three-dimensional object or scene that appears to float or come alive in space. Hologrammes are often appreciated for their realistic and detailed representations, providing a unique visual experience that goes beyond traditional two-dimensional images or photographs. They find applications in various fields, including entertainment, art, research, and security, among others, due to their capacity to convey volumetric and dynamic visual information.

Etymology of HOLOGRAMME
The word "hologramme" is derived from the combination of two Greek roots: "holos" meaning "whole" or "entire" and "gramma" meaning "message" or "writing". The term was coined in the mid-20th century by Hungarian-British physicist Dennis Gabor, who invented holography. The word "hologramme" is the French variation of the word "hologram", which refers to a three-dimensional photographic image created using lasers.
