Abstract

This paper focuses on the experimental combination of two topical technologies: (1) the joint transform correlator (JTC) and (2) the wavelet transform (WT). The result is an optical wavelet processor utilizing liquid crystal televisions (LCTV) as phase-only spatial light modulators (SLM) in a JTC architecture. The mathematical formalism of the optical wavelet processor is presented followed by simulations involving amplitude- and phase-only SLM operation.
