摘　　要：在对单光子探测过程中后脉冲现象进行理论分析的基础上,通过实验对后脉冲概率进行了统计测量,这种方法与其它方法的不同之处在于不需要更多的实验仪器,而测量得到的实验结果与其他实验方法的不同。这里对实验条件的确定进行了分析和讨论。In the paper, the afterpulse probability has been measured by using photon statistical method on the base of theoretical analysis for the single photon detection. It is found that the measured afterpulses obey Gausslan distribution, and the Gauss curve will be shifted left with increasing incident photon intensity. We have analyzed the physical process of the phenomenon and obtained the afterpulse probability of our single photon detector. Compared with the common start-stop method, this robust photon statistical method has the advantages of direct measurementand not requiring additional equipments.
