| Abstract: | In this paper we apply the encoding in mathematics to the optical principle and propose a new optical matrix multiplication system with negative binary encoding by using four-wave mixing of photorefractive crystal. Its principle is introduced and its operating performance is analyzed. The research shows that the matrix encoding of the system is easy and it can realize the matrix multiplication cosmically. And it is useful for the research on optical calculation. |
