Paper Abstract

This paper discusses a method for reconstructing images using a joint transform optical correlator (JTC) architecture. The architecture employs a single liquid crystal television (LCTV) as the spatial light modulator (SLM) operating only on the phase of the incident coherent light. The wavelet transform (WT)-based image decomposition and synthesis is performed in the transform plane instead of the correlation, or wavelet transform plane. While the method presented here does not yield a true reconstruction in the strictest sense, it has many useful characteristics. Experimental results are presented as well.
