Architectural prototypes and algorithms for performing many simultaneous complex correlations between external data and data stored on optical disks are presented. External data are modulated onto an addressing light beam acoustooptically. Analog cor

We have demonstrated and analyzed an analog electronic constant false alarm rate processor that discriminates against distributed clutter for an acoustooptic correlator of a potentially large time-bandwidth product.

An acoustooptic technique was used to design and construct a prototype of a processor capable of multiplying a 128 x 128 complex-element matrix by a 128 complex-element vector. The device was specified to execute 10(5) matrix-vector products per seco

Optical associative, parallel-processing architectures are being developed using a multimodule approach, where a number of smaller, adaptive, associative modules are nonlinearly interconnected and cascaded under the guidance of a variety of organizat

A judicious selection of polymer materials for the fabrication of a deformable-membrane light modulator (e.g., the photoemitter membrane light modulator) will enhance its speed. A polymer with a low surface energy decreases the device response time b

Three different optical systems are developed for efficient evaluation of a triple-matrix product of the form [U][G][V]. One system uses a purely space-integrating architecture, whereas the other two use hybrid time- and space-integrating architectur
