Title: Optical Pattern Recognition IV Conf. Date: 13-14 April 1993 Conf. Loc: Orlando, FL, USA Conf. Sponsor: SPIE Treatment: Practical; Experimental Abstract: Recent advances in coupling liquid crystal spatial light modulators (SLMs) with silicon VLSI chips have opened new opportunities in optical parallel processing and computing. It is now possible to construct compact, reliable, and reconfigurable optical hardware for industrial use. The authors have chosen the task of road sign recognition, with emphasis on speed limit signs, to demonstrate the feasibility of such an optical processor which uses fast switching elements based on ferroelectric liquid crystal technology.
