便携式能见度测量仪设计

Design of Portable Visibility Meter

能见度是一个重要的气象观测要素,在航天、民航、公路等交通运输,以及环境监测等领域有着非常广泛的应用.本文利用红外LED灯设计了一种便携式前向散射式能见度仪,实现实时的大气能见度测量.样机试运行结果表明,其测量精度大约为17%.

Visibi li ty is an indicator to ref lect the transparency of the atmosphere, and also is the mete-orological observation conventional project. It has significant impacts on sailing, aviation, land transporta-tion and military activities. In this paper, a prototype of the visibility meter is developed. The prototype＇s test results show that the measurement accuracy is about 17%. It is shown that the visibility meter has a good accuracy and stability.
