针对透射式能见度测量系统占地面积大、长距离光路上不能有遮挡的不足，提出一种多次反射法透射式能见度测量系统。利用反射镜组构成开放式采样气室，使光线多次反射达到测量所需的光程，具备透射法能见度检测高精度优点的同时，大大缩小系统占地面积；采用位移调节器实现差分大气消光系数测量，具有抗环境污染能力强和测量灵敏度可调等独特优点，有效提高系统的适应性和可靠性。对设计的系统进行精度估算，证明了方法的可行性，为能见度测量提供了新方法。

This paper presents a multi-reflection transmission method based atmospheric visibility measurement system in view of such disadvantages as big area occupation and no obstruction on a long-distance lightpath for a traditional transmission visibility meter. The system employs an array of reflectors to construct an open air chamber and to achieve the needed optical distance, which can reserve high-precision visibility detection of transmission method and dramatically decrease area occupation. The system also employs a displacement regulator to achieve differential measurement of atmospheric extinction coefficient. The system has such unique advantages as strong contamination resistance capability and adjustable measurement sensitivity. Its accuracy estimation proves that its design method is feasible and a new method is provided for visibility measurement.
