Abstract

The optical matrix computing often plays a very important role in optical digital processing, many transformation and information processings in optics can be converted into a group of basic matrix multiplications¹. Now, many approaches to implement such calculations have been provided^2-4. But to all the existed schemes and systems, the difficulty is the long time sequence and the lower accuracy obtained, as well as a rather complicated system is required. In this paper, we have tried to use optical symbolic substitution method⁵ combined with the calculation of outer product of matrices to solve the multiplication of matrices. Preliminary experimental result has been obtained successively.
