摘要： A technique for performing multiplication oriented optical digital computations in which a pair of identical primary frequency coherent beams of light are directed off-axis through a second harmonic generating crystal to produce an on-axis frequency doubled (i.e. second harmonic) output signal. Each primary beam is encoded with one of the quantities to be multiplied producing an output beam containing the product of the two quantities. The output beam is detected by an array type detector. The technique can be used in performing time integration applications as well as spatial integration applications. For space integration applications a cylindrical lens is positioned in front of the array detector. Multistage operations are realized using a parameteric frequency down conversion and amplification scheme.

摘要： An optical computer apparatus and method in which binary operations are implemented by utilizing optical elements to perform AND-OR-INVERT operations of the binary operation and combinatorial logic elements perform the remaining operations. Preferably, a pair of acousto-optic cells are energized by binary data, which data are supplied by combinatorial logic, and which cells modulate light rays that are focused on detectors which determine the presence or absence of light. The particular combination of data supplied by the combinatorial logic is a function of the operations remaining in the desired binary operation once any AND-OR-INVERT functions have been implemented by way of optical structures. Further, the propagational time through the acousto-optic cells is utilized to implement systolic type implementations of binary functions.

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： 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.
