title: Bistable optical spatial device using direct optical feedback.
abstract: Analysis and implementation of a set of optically controlled optical flip-flops on the surface of a liquid-crystal spatial- light modulator (SLM) are presented. The elementary system consists of a pair of image elements on the SLM whose input and output are coupled to each other by purely optical means. The coupling is established simultaneously and independently for all pairs of elements on the SLM.
