Abstract

The inner-product approach^1,2 is an alternative way of performing optical implementation of neural associative retrieval. With the inner-product approach, the interconnection matrix is realized by directly storing the binary memory vectors in two spatial planes in tandem. Thus there is no saturation problem with the spatial light modulators realizing the interconnection matrix, and the precalculation of the outer-product interconnection matrix is not needed. Moreover, the optical storage space is about an order of magnitude smaller compared with that of the outer-product approach.
