摘要/Abstract

摘要： 鉴于大气能见度的直观特性和红外光电技术的迫切需求，提出了一种大气红外能见度的计算与测量方法，并研制了一套大气红外能见度测量仪器，该仪器以1064 nm波长激光作为光源，以Xenics红外相机为探测器测量红外能见度。暗场处理时利用传统的背景扣除方法和移位相减法进行对比实验，能见度反演过程中用斜率法和Klett积分法同时对测量结果进行处理，结果表明该系统测量出的红外能见度与Belfort能见度仪测量结果基本一致，相关系数达80%以上，表明红外能见度的计算和测量结果是可靠的。

Abstract: In view of the intuitive characteristics of atmospheric visibility and the urgent need of infrared photoelectric technology, a calculation and measurement method of atmospheric infrared visibility is proposed, and an atmospheric infrared visibility measuring instrument is developed. The instrument uses 1064 nm wavelength laser as the light source and Xenics camera as detector to measure infrared visibility. A traditional background subtraction method and the shift-phase subtraction are used to carry out the contrast experiment when dark background processing is carried out. The measurement results are also processed by the slope and Klett integration method in the process of visibility inversion. Results show that the infrared visibility measured by the system is basically the same as that of the Belfort visibility meter, and the correlation coefficient is more than 80%, which shows that the calculation and measurement results of infrared visibility are reliable.

Key words: infrared atmospheric visibility, extinction coefficient, linear regression, Klett integral method, shift subtraction method
