从能见度定义出发,推导出测试光波长和能见度的关系。对大气衰减特性研究表明,按照常规方法计算能见度会导致系统偏差,这些偏差依赖于测试光源的光谱特性,不同厂家、不同测试方法偏差不同。通过国外的一系列对比实验证明该系统偏差的存在,最后提出了通过研制能见度标准来消除系统误差的解决方案。

The relationship between testing optical wavelength and visibility is derived from the definition of visibility.Study on atmosphere attenuation shows that the conventional method of computing visibility will cause system deviation, which depends on the relevant spectral characteristics of testing light and is different for different vendor and testing method.A series of foreign experiment comparisons are provided to prove the existence of the system deviation.Finally, the solution to eliminating the system deviation is proposed by developing a new MOR standard.
