摘要

A discrete-time probability model is proposed to predict the detection performance of the Geiger-mode avalanche photodiode array. This model is established by considering multiple influencing factors, and crosstalk is characterized in the form of a transition matrix during the modeling process. The verification experiment shows that the results are consistent with previous results for a crosstalk-free scenario. The performance analysis also indicates that the array detection performance decreases approximately linearly with the increase of crosstalk probability. When the crosstalk probability is 20%, compared with the scenario without considering crosstalk effects, the deviation of array detection probability reaches up to 27.05%.
