Optical full-parallel three matrices multiplication

Abstract

Optical systems are capable of performing high parallel computations at very high speed. This suggests the use of optical computing methods for •achieving matrices multiplication that requires handling large arrays of number in parallel manner. From this point of view, many efforts have made to implement matrix-matrix multiplications in full parallel. However, most of them require some special optical elements, such as scanning system, cylindrical lens array or some undesirable elements, only two optical systems for multiple matrices multiplication are constructed by some common optical elements such as spherical lens or cylindrical lens, but they are still very complicated.
