Paper Abstract

The wavelet transform is a useful transformation for signal processing and compression, however, when it is calculated digitally, it requires a high amount of computation effort. Optics has solved partially this problem by implementing the hybrid wavelet transform in which the set of scaled wavelet mother functions is discrete but the shift is continuous. We use white light illumination to obtain a 2-D, fully continuous, on-axis wavelet transformer. Experimental demonstrations are given.
