Paper Abstract

From physical analysis, we explained that the phase matching is more important than the amplitute in match filtering. Thus the amplitute of Fourier transform of object can be modified to reduce the dynamic range, while the phase information keeps unchanging. The holographic match filter was made by dichromatic gelatin. High efficiency correlation can be obtained by this method.
