在固体脉冲激光测距中,采用光电倍增管作为探测器件应从概率接收角度来研究接收系统的探测能力。本文重点讨论了匹配接收情况下,光电倍增管量子效率、接收孔径面积、接收视场角、干涉滤光片带宽、距离选通等和探测能力的关系。结合具体接收参 In solid-pulsed laser ranging, the use of photomultiplier tube as the detection device should be probed from the perspective of probability to receive the detection system receiving capacity. In this paper, we mainly discuss the relationship between the quantum efficiency of the photomultiplier tube, the area of ​​the receiving aperture, the receiving angle of view, the bandwidth of the interference filter, the distance gating and the detection capability under the condition of matched reception. With the specific reception parameters
