phase-modulated hologram
1Holography — (from the Greek, ὅλος hólos whole + γραφή grafē writing, drawing) is a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the… …
2Light-emitting diode — LED redirects here. For other uses, see LED (disambiguation). Light emitting diode Red, pure green and blue LEDs of the 5mm diffused type Type Passive, optoelectronic Working principle Electr …
33D scanner — A 3D scanner is a device that analyzes a real world object or environment to collect data on its shape and possibly its appearance (i.e. color). The collected data can then be used to construct digital, three dimensional models useful for a wide… …
4Liquid crystal display — LCD redirects here. For other uses, see LCD (disambiguation). Reflective twisted nematic liquid crystal display. Polarizing filter film with a vertical axis to polarize light as it enters. Glass substrate with ITO electrodes. The shapes of these… …
5Field emission display — A field emission display (FED) is a display technology that incorporates flat panel display technology that uses large area field electron emission sources to provide electrons that strike colored phosphor to produce a color image as a electronic …
6Holographic associative memory — is part of the family of analog, correlation based, associative, stimulus response memories, where information is mapped onto the phase orientation of complex numbers operating. It can be considered as a complex valued artificial neural network.… …
