Abstract:A new method for fingerprint identification using a real-time high efficiency joint transform corrlator(JTC) was proposed.In this system,a right angle prism is used to input fingerprint image in real-time,a multi-focus hololens is used to produce joint transform power spectral array so that an enhanced optical correlation signal can be obtained at the output plane.The experiment results show this method is applicable to identification of fingerprint image with a little distortion owing to the finger press part and force different.
