为了满足在不良气象条件下，机场飞机安全起降对能见度的观测需求，基于后向散射原理设计了一台小型激光雷达能见度仪。该系统采用具有低脉冲能量、高脉冲重复频率的二极管抽运固体激光器和具有低噪声、高量子效率的雪崩光电二极管探测器，确保了系统的测量精确性；并采用嵌入式计算机作为系统的控制和数据处理核心，实现了对系统工作时序的控制。经过多次外场测试，能见度测量数据总体误差小于15％。结果表明，该系统具有较高的探测精度，完全满足国际民航组织对于能见度观测设备精确度的要求。

In order to satisfy the safety requirement of aircraft taking off and landing under bad weather conditions, a portable lidar visibility meter was designed based on the principle of atmospheric backscatter.Diode pumped solid-state laser with low pulse energy and high pulse repeat frequency and avalanche photo diode detector with low noise and high quantum efficiency were adopted to ensure the precision of system.Specially, the embedded computer was adopted as the core of system controlling and data processing and the timing control of system was realized.The field test results show that the system has high detection accuracy and the overall error is less than 15%.The results show that the system has high detection precision and can satisfy the safety requirements of International Civil Aviation Organization.
