    Abstract

    We present a method of using a liquid crystal television (LCTV) as a spatial light modulator (SLM) in an optical computing experiment. Using LCTVs as SLMs to modulate an image optically and combining this process with a digital computer has allowed implementation of various image-processing algorithms that have only been demonstrated in the digital domain. In particular, we are using an LCTV as an SLM for the hybrid optical implementation of a homomorphic filter to remove image shading.
