Paper Abstract

A novel optical wavelet processor is introduced. Generic wavelet functions, consisting of both amplitude and phase information can be optically synthesized using two cascaded Liquid Crystal Television Spatial Light Modulators. An innovative ternary-valued shape discriminant wavelet filter and its optical implementation is also introduced. Experimental demonstrations of multitarget classification using both a 2D Morlet wavelet filter and a ternary wavelet filter are also reported. The experimental results show that the wavelet filters are superior in discrimination than that of the conventional correlation technique.
