Abstract

A Haar wavelet transform with a Vander Lugt optical correlator is described. Optical Haar wavelet matched filter is created by using of computer-generated holography (CGH′s). Experimental results for 2-D wavelet transform are obtained. The main advantage of the proposed method lies in that any types of wavelet matched filters can be fabricated and their 2-D wavelet transform can be realized.
