摘　　要：设计了基于FPGA的多通道符合计数器,此设计将符合窗口时间的设定集成于FPGA器件中,因此集成度更高,并且通过实验进行了模拟单光子探测器脉冲信号的符合测量,计数误差为0.02%,能用于对纠缠光子对的判定.Based on FPGA a multi-channel coincidence counter is designed,in which the setting of window time is integrated in FPGA in order to improve the integration of the system. Furthermore,the coincidence counting experiment is conducted by using signal generator to simulate the pulse signal produced by single photo detector. Results show that the error of measurement is 0. 02%,and it can be used to judge the entangled photon pairs.
