The Scophony Spatial Light Modulator
SPIE Proceedings, 1984The Scophony scanner uses the same optical elements as the more familiar flying spot scanner: a rotating polygon mirror, an acoustooptic (A/0) modulator, and a laser light source. The flying spot scanner is designed to construct its image a pixel at a time; no more than one pixel is illuminated at any given instant.

Scophony Spatial Light Modulator
Optical Engineering, 1985An alternative to the conventional flying-spot scanner architecture is the Scophony scanner. The Scophony scanner uses the same optical elements as the more familiar flying-spot scanner: a rotating polygon mirror, an acousto-optic (A/O) modulator, and a laser light source. The flying-spot scanner is designed to construct its image a pixel at a time; no

Publisher Summary This chapter discusses spatial light modulator, which comprises a photocathode, micro channel plate, mesh electrode, and a LiNbO3 crystal in a vacuum-sealed tube. The device is a transducer for incoherent to coherent light conversion; it is highly sensitive and can be used over a wide wavelength range. It can also be used to perform

Spatial light modulators and their applications
SPIE Proceedings, 1991An optical neural network system using a microchannel plate spatial light modulator (MSLM) and a computer-generated hologram (CGH) displayed on a liquid crystal TV (LCTV) display device are described. In the optical three-layer neural network, the back-propagation learning algorithm is successfully demonstrated with the uniformity of +/- 35% in ...

The success of liquid crystals in visual display devices has assured their commercial viability and made them common in our everyday use. However, their uses and applications go well beyond the displays used on handheld devices. Projection systems, similar to displays, also make use of liquid crystals, but in the form of spatial light modulators.

Proceedings of the IEEE, 1977
Near real-time reusable spatial light modulators for coherent optical data processing are reviewed. The PROM, liquid crystal, and electron beam addressed DKDP and oil film light valves appear to be the most promising devices for coherent optical data processing.

Miniature spatial light modulators
SPIE Proceedings, 1990ABSTRACTSpatial light modulators (SLM) are examined from the viewpoint of miniaturization and optical correlation systems. The structure and behavior of a silicon-chip active-matrix-addressed ferroelectric liquid-crystal SLM is presented. Theresponse of an amorphous-silicon optically addressed nematic liquid crystal SLM is reported. 1.

Analog spatial light modulator
Soviet Journal of Quantum Electronics, 1983An analysis is made of the construction, operating principle, and possible applications of analog spatial light modulators performing the function of a rotating slit and intended for optical data processing systems. A report is given of the characteristics of prototype modulators in which liquid crystals are used and a theoretical analysis of their ...
