摘要提出了一种基于光束扫描方式测量透过率计光路的新型对准系统。该系统在沿两个垂直方向扫描的同时控制探测光束和接收视场。然后，该系统计算发射器和接收器的方位角，以确定光路的精确对准。实验表明，该方法可以在不到10min的时间内确定对准角度，方位误差小于66μrad。该系统还具有准直精度高、过程自动化、安装简单等特点。
Abstract This paper proposes a novel alignment system based on the measurement of optical path using a light beam scanning mode in a transmissometer. The system controls both the probe beam and the receiving field of view while scanning in two vertical directions. The system then calculates the azimuth angle of the transmitter and the receiver to determine the precise alignment of the optical path. Experiments show that this method can determine the alignment angles in less than 10 min with errors smaller than 66 μrad in the azimuth. This system also features high collimation precision, process automation and simple installation.
