Abstract
Optics has advantages for overcoming limitations arising when applying existing electronic technologies to real-time parallel computation. In particular, spatial light modulators (SLMs) permit simultaneous storage, multiplication, and/or complex interconnection. A simple diagnostic expert system uses Bayes theorem to recursively update the probabilities of various hypotheses given additional sensor input information. The 'a priori' probability matrices are stored in SLMs which provide matrix-vector multiplication and interconnection. High speed permits the optimum determination of which sensor should be polled next.
