Abstract:
PCT No. PCT/GB90/01782 Sec. 371 Date Jun. 11, 1992 Sec. 102(e) Date Jun. 11, 1992 PCT Filed Nov. 20, 1990 PCT Pub. No. WO91/07714 PCT Pub. Date May 30, 1991.A neural network has inputs formed by square array of optical modulators Mij and outputs by optical detectors Dij coupled to threshold comparators. A holographic plate includes a spatial modulator whose elements are controlled by a controller to form an array of optical beams from a coherent optical source. Each optical beam optically interconnects a modulator Mij with a respective detector Dij. The weight values of the neural network are provided by the intensities of the optical beams. This obviates the need for an optical weighting mask between an array of light emitting diodes and a detector array allowing a higher density of lower power consumption components and reprogrammability of the network.
