摘要：

简述单光子探测器对于激光云高仪研究的重要作用。在了解单光子探测器SPAD基本工作原理的基础上，搭建SPAD的被动抑制电路，实验得出SPAD的死时间在2 ?s以上，只能适用于单光子计数率小于500 kHz的场合。为了减少单光子探测器的死时间，提高单光子计数率，设计了雪崩被动淬灭电压主动恢复的混合抑制电路，通过精密的时序控制，探测器的死时间缩短为100 ns，单光子计数率上升至10 MHz。理论上激光云高仪的空间分辨率可达15 m，单光子探测器SPAD混合抑制电路对于激光云高仪的工作性能以及顺利研制有着重要意义。

Abstract:

The important role of single-photon detector for laser ceilometers is briefly introduced. On the basis of the basic working principle of single-photon detector (single-photon avalanche diode, SPAD), a passive suppression circuit of SPAD is built. The experiment shows that the dead time of SPAD is above 2 ?s, only applicable to the occasion when single-photon counting rate is less than 500 kHz. In order to shorten the dead time of the single-photon detector, improve single-photon counting rate, the mixed suppression circuit of avalanche passive quenching and voltage active recovery is designed. Through the precise timing control, the dead time of the detector is shortened to 100 ns, single-photon counting rate up to 10 MHz. In theory, the spatial resolution of the laser ceilometer can be up to 15 m, mixed quenching circuit of single-photon detector SPAD for the performance of laser ceilometer and smooth development has important significance.

Key words: laser ceilometer, single-photon detector, avalanche photodiode, mixed quenching technology
