The general problems and limitations of photoaddressed liquid crystal spatial light modulators (SLMs) are discussed, and experimental results are presented. A GaAs wafer photoaddressed nematic liquid crystal SLM is described in detail with experimental results. The edge enhancing or differentiating SLM is discussed, and the results of GaAs photoaddressing are reported. The preliminary experimental behavior of photoaddressed ferroelectric liquid crystal SLMs is described.
