title: Photoaddressed liquid crystal edge-enhancing spatial light modulator.
abstract: Pattern recognition via optical correlation generally requires an incoherent-to-coherent input image converter and benefits from edge enhancement of the input image. We have created a photoaddressed nematic liquid crystal differentiating spatial light modulator that fulfills both these functions. Developments in photoaddressing are discussed, and experimental results on edge enhancement are presented.
