| 摘 要： | 对于直接探测三维成像激光雷达，采用光子计数探测器可以响应单光子水平的目标回波，从而大大提高探测效率。研究的光子计数三维成像激光雷达采用盖革模式雪崩光电二极管（APD）作为探测器。首先分析了回波光子探测模型，并根据此模型讨论了激光雷达探测概率和测距模式。在理论分析的基础上，设计了一套光子计数三维成像激光雷达系统，对一些选定目标进行了测距和三维成像实验，并对实验结果进行了分析。

| Abstract: | For a direct-detection 3D imaging laser radar,the use of photon counting detector could greatly enhance the detection efficiency of the receiver.This paper studies the 3D imaging lidar using Geiger Mode APD.In this paper,the detection model for this laser radar is analyzed.Based on this analysis,the detection probability and rangefinding precision are discussed.Then a photon counting 3D imaging brass board system is described,and some experimental results obtained by this system are presented and analyzed. |
