Abstract : An electro-optical system for performing matrix-vector multiplication includes a mask having a plurality of elements of substantially equal resolution area disposed in a matrix of M rows and N columns, each element containing recorded discrete information as defined by its degree of opacity which is representative of a predetermined mathematical value in a known matrix. A light source is positioned to illuminate the mask and has its intensity modulated as a function of the sequential values in a N X 1, vector. A multiple photo-responsive array including M elements disposed in a column is positioned to receive the light energy transmitted by the illuminated mask and generates signals at each element commensurate with the instantaneous photo energy received at its position. A suitable means which is synchronously operative with the modulation of the intensity of the light source, sequentially develops cumulative signals corresponding to the signal information contained in each column of the mask, producing a matrix-vector multiplication result.
