Terms in Holography
Glossary Get to know a list of certain terms associated with hologram and holographic technique: Animated holograms: They are made by using time-lapse photography. The object moves between exposures. The object appears to move as the viewpoint changes when the hologram is made from these photos. They are made up of hundreds of image channels Beamsplitter: This is a device which divides the light from a laser into two separate beams-the reference beam and the object beam. Channels: They are images in a hologram which change instantly from one to another as the viewer passes by. These images can also fade or overlap as they change. Coherent light: A coherent light is made from laser and this light is of the same frequency and vibrates in phase. Computer generated hologram: This is a hologram made from a three-dimensional computer model. 2D/3D Hologram: The hologram is made of multiple 2D layers with hologram images placed one behind another with vi...
