82Display contrast — Contrast in visual perception is the difference in appearance of two or more parts of a field seen simultaneously or successively (hence: brightness contrast, lightness contrast, color contrast, simultaneous contrast, successive contrast, etc.).… …
83Computer-generated holography — (CGH) is the method of digitally generating holographic interference patterns. A holographic image can be generated e.g. by digitally computing a holographic interference pattern and printing it onto a mask or film for subsequent illumination by… …
84Multiscopy — In contrast with 3D binocular stereoscopy (displaying a 3D scene via a left eye and right eye angle), 3D multiscopy displays multiple angles at once.[1] This allows a viewer to move their head around the 3D subject to see it from different angles …

87Nixie tube — The ten digits of a GN 4 Nixie tube. A nixie tube is an electronic device for displaying numerals or other information. The glass tube contains a wire mesh anode and multiple cathodes. In most tubes, the cathodes are shaped like numerals.… …
88Dispersion (optics) — This article is about dispersion of waves in optics. For other forms of dispersion, see Dispersion (disambiguation). In a prism, material dispersion (a wavelength dependent refractive index) causes different colors to refract at different angles …
