摘要： Digital computation is performed on an integrated optical circuit level using optical threshold logic elements. Each input and output optical beam of each element occupies a separate channel and interacts with only one switching component thus assuring true digital computation. These circuits provide access to the entire class of logic functions routinely utilized in electronic digital computers. The integrated optical devices are programmable and are capable of high speed logic operations and reliable digital operation in a complex network.

摘要： The improved electrooptic signal processing relies upon matrix-matrix multiplication using twos complement arithmetic. A source of pulse collimated light illuminates two two-dimension spatial light modulators that operate in a reflective mode through a polarizing beamsplitter. Each of the spatial light modulators has a matrix of optically encoded information of numbers in the twos complement binary representation so that a mixed binary representation of signals is generated within the two-dimensioned photodetector array. The mixed binary representation signals are decoded to a twos complement binary representation or a decimal representation to be useful for more conventional processing techniques. The twos complement arithmetic when incorporated with the electrooptic architecture provides for a convenient means for handling bipolar numbers, avoids the need for matrix partitioning when the matrices are real and offers a means to improve accuracy over conventional optical analog techniques.

摘要： A method of producing single-class and multi-class composite classification maps from multispectral data is provided. The multispectral data is transformed into a binary matrix format which is then encoded on an optical medium such as photographic film. The encoded data is holographically correlated with coded patterns representing selected spectral signatures to produce signal-class classification maps. Several single-class maps are optically superimposed to produce multi-class composite classification maps.

摘要： The present invention relates to the optical processing of information using a magneto-optical light modulator to spatially modulate light energy in accordance with the information. The magneto-optical light modulator includes a thin magnetic film having a spatial magnetic pattern in accordance with the information. The light energy is directed to the thin magnetic film to produce variations in the characteristics of the light energy in accordance with the spatial magnetic pattern. After the light energy has been spatially modulated the light energy is further processed using optical lenses so as to produce a desired transform of the spatially modulated light energy.

摘要： A method of processing information by combining regions of a radiant energy beam which have been modulated according to the information. The combination is performed according to a pattern of phase relationships which produces the desired function of the information. A preferred apparatus for performing this method includes a source of coherent radiation, means for phase modulating regions of the beam and a holographic processing element which corresponds to an array of points having the selected pattern of phase relationships. The output may be determined by a second modulating means associated with a subsequent processing stage or by a readout means.
