摘　　要：介绍了一种利用激光测量跑道水平及斜视能见度的原理与方法。通过合作目标的使用 ,使得能够较简单地实现对斜视能见度的测量且大幅度地提高了仪器回波信号的幅度与灵敏度 ,并由此确定了仪器可选用PIN光电二极管作光电转换器件 ;通过透射率标尺的引入 ,改善了仪器对能见度测量的相对误差曲线 ,提高了能见度、尤其是低能见度的测量精度。能见度的测量精度优于 1 2 %。This paper presents the principle and measuring method of a laser instrument used to measure runway horizontal visibility and approach visibility. By means of the co operation target,the instrument could simply measure approach visibility,greatly increase amplitude of receiving signal and improve its sensitivity.PIN photodiode can be used as photoelectrical transformation unit to detect the amplitude of receiving signal. By means of transmission ruler,curves of relative errors are optimized. Measurement precision of visibility,especially lower visibility is improved.Measurement error of runway horizontal visibility and approach visibility is less than 12%.
