DIGITAL OPTICAL COMPUTING WITH MAGNETOOPTIC 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 flexibi lity in algorithm development. The hardware used consists of two compu ter-controlled magneto-optic spatial-light-modulator arrays in conjunc tion with a CCD detector array as the computational hardware. Algorith ms for binary-processing tasks are presented. We used magneto-optic sp atial light modulators for parallel processing in a way that exploits multivalued output. Also, in carrying this evaluation out, we develope d a new and efficient multiplication algorithm. Multiplication is an i mportant operation in many digital systems, and the design of fast mul tipliers is of great interest to computer scientists and engineers. Th e speed of this computing system is evaluated.
