摘　　要：设计和实现了云南天文台1.2 m望远镜10 Hz共光路漫反射激光测距控制系统,包括激光器、信号探测器和测时设备等的控制。并将系统应用于实际观测中,使用结果表明系统运行正常,且已成功实现了部分空间碎片的漫反射激光测距。将测时设备换为事件计时器后,该系统可直接用于激光测月试验。Both traditional and l kHz common optical-path Satellite Laser Ranging （SLR） techniques have been implemented and applied on the 1.2m telescope of the Yunnan Observatory several years ago. A diffuse-deflection laser ranging system was designed for it recently, and a 10Hz common optical-path diffuse- reflection laser ranging control system has also been designed and installed there. The system includes a laser, returned laser signal detectors, and timing devices. The hardwares of this control system include a Field Programmable Gate Array as the key component, and the user applications are developed with the Visual C＋＋. This system has been used to observe satellites and space debris. Observation results indicate that it can function normally ahd successfully achieve laser ranging. Finally, we show that it can be directly applied to lunar laser ranging experiments after the SR620 timing device is changed to an event timer.
