摘要
提出一种用３ｆ多路（３×３）光学相关器实时识别指纹的新方法，其特点是能把光学傅里叶变换（ＦＴ）获取的频谱特征数据同光学子波变换（ＷＴ）结果相结合进行目标识别．计算机模拟结果和实验结果表明。
A new method which uses 3 f multiple (3×3) optical correlator to implement real time fingerprint recognition was presented.The feature of this method is that it can combine the optical Fourier transform with wavelet transform to implement real time target recognition. Computer simulations and experimental results show that the method is efficient in fast processing and recognition of complicated fingerprint images.
