| 摘 要： | 提出一种用高效联合变换相关器(JTC)作实时指纹识别的方法。用直角棱镜作为指纹的实时输入装置，用多焦点全息透镜产生目标指纹和参考指纹的联合变换功率谱阵列．在输出面上得到增强和相关信号。实验表明．这种识别方法特别适于由于手指按压部位不同和用力大小不同而产生少许变形的指纹图像的识别。

| 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. |
