Abstract

Image-edge enhancement has been demonstrated with photorefractive crystals and optically addressed spatial light modulators (OASLMs) with nematic liquid crystals.¹,² These methods used devices that operate with 10–100 ms response times. We report analysis and experimental results of the edge enhancement of images by means of an amorphous silicon/ferroelectric liquid-crystal OASLM.
