Optical signal processing
Abstract
Optical signal processing makes possible rapid coordinate transformations, optical pattern recognition, and matrix-matrix multiplication. In the present contract, DSI has demonstrated several significant accomplishments. Among these are: (a) the design and operation of a spatial-frequency-multiplexed coherent optical processor; (b) the application of outer product operation to matrix-matrix multiplication; and (c) the description of three methods for performing Hankel transforms with optical or digital processors.
