A match filtering method with high efficiency
The physical justification of pattern recognition with a phaseonly match filter is analysed in this paper. In the experiment the amplitude of Fourier transform of object is modified to reduce the intensity dynamic range, while phase information is preserved. The holographic match filter was made by dichromatic gelation. The high emeiency correlation is obtained by using this method.
