提出了一种利用光折变晶体的动态存取性能构成自适应联合变换相关器的方法，其中光折变晶体用于参考图像的时间延迟和相继更新。由该方法可实现全光学目标跟踪系统，在任一时刻只有单一图像输入该系统，该时刻直接透射的目标像与晶体再现的前一时刻的目标像产生相关并给出目标的运动信息。进行了目标跟踪的初步实验，证实了该方法的正确性和有效性
A method of adaptive combined transform correlator using dynamic access properties of photorefractive crystals is proposed, in which photorefractive crystals are used for the time delay and subsequent updating of reference images. By this method, an all-optical target tracking system can be realized. Only a single image is input to the system at any one moment. The directly transmitted target image at this moment is related to the generation of the target image at the previous moment of the crystal reproduction and gives the movement information of the target. A preliminary experiment on target tracking has been carried out, which proves the correctness and effectiveness of this method
