Abstract
A two-dimensional wavelet transform is implemented by a bank of wavelet transform filters in the Fourier domain. An optical N4 multichannel correlator architecture is proposed to perform parallel optical 2-D wavelet transforms. A holographic recording scheme is proposed to implement such a wavelet transform filter array. The optical experimental results are presented using the computer-generated transmittance masks as the wavelet transform filters.
