Abstract
An optical computing system is provided for performing a linear multiplication operation involving a matrix with bipolar values. A plurality of beams representing the values of a N.times.1 column matrix Q illuminate an optical mask having elements disposed in a two-dimensional (M+1).times.N array. Each element of the first M rows of the mask represents the offset of the value of a corresponding element in a known M.times.N matrix by a scalar constant c. Each element of row M+1 of the mask represents the value c. An array of photodetectors collects the light passing through the mask, with the light from each row of elements detected by a respective photodetector. The outputs of the first M photodetectors represent the product of Q and M after M has been offset by c. The output of photodetector M+1 represents the scalar value produced by the multiplication of Q and a row matrix represented by row M+1 of the mask matrix. This scalar value can be used to adjust the outputs of the first M photodetectors, the result being equivalent to Q.multidot.M.
