| Abstract: | Fingerprints recognition, which is accomplished through computers, is an important biological identification tech- nique. In order to improve the accuracy and instantaneity, we set up a joint transform correlation holograph system that mainly consists of Fourier lens and a spatial light modulator. This system records the spectrum of the holographs and finger- prints can be recognized in real-time by comparing the pixel intensities. |
