Digital optical computing with magneto-optic spatial light modulators: a new and efficient multiplication algorithm

Digital optical computing executed on arrays of binary data can offer parallel processing and multivalued output, which permits more flexibility in algorithm development. The hardware used consists of two computer-controlled magneto-optic spatial-light-modulator arrays in conjunction with a CCD detector array as the computational hardware. Algorithms for binary-processing tasks are presented. We used magneto-optic spatial light modulators for parallel processing in a way that exploits multivalued output. Also, in carrying this evaluation out, we developed a new and efficient multiplication algorithm. Multiplication is an important operation in many digital systems, and the design of fast multipliers is of great interest to computer scientists and engineers. The speed of this computing system is evaluated.
