摘要
We designed and built a high-capacity neural network based on volume holographic interconnections in a photorefractive crystal, We used this system to implement a Kohonen topological map. We describe and justify our optical setup and present some experimental results of self-organization in the learning database. (C) 2001 Optical Society of America.
