Paper Abstract

For an array of independent picture elements on a spatial light modulator (SLM), we present a configuration where each element is in one of two stable equilibrium states. Their stability as well as the means for switching between them is exhibited theoretically and experimentally. The distinguishing feature of the array of the independent bistable switching elements is that the implementation of each involves only a single active element in the feedback loop so that optimum use of the active area of the SLM is made.
