Abstract
An optical processing system performs matrix-matrix, matrix-vector, and vector-vector multiplication. Element product formation is accomplished by the time integration of a detector array which converts light signals into electrical signals. Inner products are formed by the spatial integration of a cylindrical lens which focuses modulated light onto the detector array. Modulation of the light is accomplished by bit-serial modulation of the light sources with one element value in twos complement form, and by bit-serial modulation of an acousto-optic cell by the other element value in twos complement form. A multi-channel systolic embodiment permits a complete vector quantity formation without the need to enter modulation data separately for each inner product of the vector.
