| Abstract: | A hybrid optical joint transform correlation system based on optical wavelet transform differentiation preprocessing is proposed.It can realize wavelet transform differentiation preprocessing and joint transform correlation recognition in real time with the same optical architecture.The experiment results shows:this system can gain very sharp correlation peaks and obviously raise the joint transform correlator's recognition ability. |

| Keywords: | Optical wavelet transform Image differentiation Joint transform correlator Correlation recognition |
