Paper Abstract

The theory of wavelet correlation and the associative characteristic of volume holographic storage in a photorefractive crystal were introduced to construct a novel multichannel wavelet correlator. With a spherical wave as the reference beam, the system was more compact and easy to be miniaturized and utilized. Its application in fingerprint identification was studied, and experimental results were given.
