A digital acousto-optic device for performing vector-matrix multiplication. The device comprises two multi-transducer acousto-optic cells imaged onto each other. The first cell receives the elements of the input vector in parallel. The second receives the elements of sequential row vectors of the matrix in parallel. The data in the two cells act to modulate a light beam passing there through. The modulated light beam is detected to produce an output data stream containing the elements of the output vector. The invention uses binary coded data for high accuracy.
