摘　　要：基于像增强器的激光雷达是探测大气参数的重要工具。在这种雷达系统中,像增强器的快门控制精度对测量结果的精度有着十分重要的影响。针对这种情况,设计了一个像增强器快门控制系统,该系统能根据实际需要精确地控制快门何时打开以及开门时间的长短,保证雷达获得的数据具有较高的可靠性。该控制器可以胜任多数带有开门时间控制的图象传感器的激光雷达系统,具有控制精度较高、时间调节的范围比较大等特点,具有较强的实用价值。Lidar based on image intensifier is one of the most important tools in the measurement of atmospheric data profile. In this system, the control accuracy of the shutter determines detecting precision. In order to more reliable data, a shutter control system is design to open and close the shutter accurately as need. In this way, the reliability of data is ensured. This controller is also can be used in the lidar system that use image sensor with shutter. It owns these characteristics： high precision and wide range of time regulation. Therefore, this system processes high practical value.
