Performance evaluation of spatial light modulators
Applied Optics, 1979An experimental test procedure and associated theoretical formulations are described for the evaluation of spatial light modulators (SLMs) for coherent optical computing. The experimental data included were obtained by us on Hughes liquid crystal and photo DKDP SLMs among others.

Photorefractive Spatial Light Modulator
SPIE Proceedings, 1990A novel concept for implementing a high resolution spatial light modulator using a thin slab of photorefractive crystal is described. Experimental demonstration as well as an analysis of the operation and performance of the device are given.

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.

Photovoltaic spatial light modulator
Journal of Applied Physics, 1991A novel concept for implementing a high-resolution spatial light modulator using a thin slab of photorefractive LiNbO3 crystal is described. This method uses the photovoltaic effect to impress phase information onto the crystal without the use of holography where coherent reference beams are required.

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.

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 ...

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
