摘要： A parallel optical arithmetic/logic unit has inputs from point-light sources forming a given spatial pattern corresponding to a given separation of point sources. The spatial pattern is presented to a multiplicity of channels by an optical system formed of linear optical elements. A static filter is provided in each channel which allows energy to pass when it comes from one spatial pattern but attenuates or diverts energy from all other spatial patterns. Thus, energy will emerge predominantly from only one channel for each specific spatial pattern separated by a given separation of point sources. The desired output state of each channel may be detected to indicate the results of an optical arithmetic or logic operation.

摘要： An optical cross bar technique for logic and arithmetic operations utilizes crossed optical paths of light configured to define intersecting regions with each other corresponding to truth table or multi-level logic table inputs. The intensity of light at each intersecting region is discriminated to determine if two units of light intensity are present at each intersection, thereby indicating a particular logic state.

摘要： An optical AND gate for use in a cross-bar arithmetic/logic unit including first and second optical substrates which are configured adjacent to one another with each of the optical substrates having a respective plurality of optical paths formed thereon. The pattern of optical paths form a plurality of intersecting regions where the optical paths associated with one of the optical substrates overlaps the optical paths associated with the other optical substrate. The optical substrates are operable for transmitting an incident light beam there through so as to produce an output at one of the intersecting regions. The optical substrates transmit the incident light beam only through the optical paths which have been illuminated by a plurality of light sources.
