Abstract : An optical matrix multiplier using two linear modulating arrays in which the columns of the first matrix to be multiplied control the modulation of one array and the rows of the second matrix control the other array. Light is directed through all combinations of elements on the two arrays and the resultant beams measured by individual elements of a two-dimensional detector array. The detecting elements time integrates the intensity of light falling on each of them, which value corresponds to an element of the product of the two matrices. The invention may be implemented among other ways with two linear electrooptical array, a linear array of light emitting diodes and a linear electrooptical array, or two Bragg cells and a pulsed light source.
