摘　　要：单光子激光雷达(又称光子计数激光雷达)具有单光子量级的探测灵敏度,相比于传统的线性探测激光雷达,能够获得更远的探测距离,已经成为激光雷达探测技术的前沿和发展趋势。然而,极高的探测灵敏度也使单光子激光雷达在探测中极易受到背景噪声光子的干扰,这在很大程度上降低了其在白天工作的性能,也极大地限制了其适用范围。文中从单光子激光雷达的探测原理出发,简要回顾了其技术发展,分析了全天时工作对单光子激光雷达探测系统的需求,在此基础上,采用一种新型的光谱滤波技术,极大地提升了单光子激光雷达在白天的探测性能。同时,还提出了一种普适性的评价模型,能够极为直观地对各种激光雷达系统的探测性能进行评价。Single photon lidar(also known as photon counting lidar) has detection sensitivity of single photon magnitude. Compared with traditional linear detection lidar, it can obtain longer detection distance, and it has become the frontier and development trend of lidar technology. However, the extremely high detection sensitivity also makes the single photon lidar highly susceptible to the interference of background noise photons in detection,which greatly reduces its performance in daytime and greatly limits its application scope. Based on the detection principle of single photon lidar, this paper briefly reviews its technical development, analyzes the requirements of all-time work for single photon lidar detection system, and a new spectral filtering technique is adopted to greatly improve the detection performance of single photon lidar in daylight. At the same time, this paper also proposed a general evaluation model, which can be very intuitive to evaluate the detection performance of various lidar systems.
