Paper Abstract

This paper describes the basic concept of the wavelet transform and proposes optical implementation of the wavelet transform using an optical correlator. The one-dimensional wavelet transform is implemented in a two-dimensional multichannel correlator with a bank of one-dimensional strip filters. In the case of the Cos-Gaussian wavelets the wavelet transform filters are the optically recorded or computer generated transmittance masks. Experimental results show detection of the transitions of the input signal by the optical wavelet transform.
