Optical realization of the wavelet transform for two-dimensional objects
David Mendlovic, Naim Konforti · Applied Optics · 1993
Real-time wavelet transformations of two-dimensional objects are implemented by use of the conventional coherent correlator with a multireference matched filter. The different daughter wavelets are spatially multiplexed with different reference-beam directions. Two experiments are described, one of them with a spatial light modulator at the input plane in order to enable the real-time property.
