Abstract

Recently many applications of the liquid crystal television (LCTV) to real-time signal processing have been reported. A basic description of the application of the LCTV to real-time pattern recognition was first reported by Liu et al. [1]. Gregory [2] later also showed a successful space invariant correlation using a LCTV as a spatial light modulator. Both methods were based on the use of a VanderLugt type complex matched spatial filter. The joint transform architecture is an alternative approach to optical pattern recognition [3]. In this paper, a new implementation of the real-time monochromatic and polychromatic joint transform correlator architecture using inexpensive LCTVs will be discussed.
