大气紫外传输特性的计算机模拟分析

Analysis of atmospheric ultraviolet transmission by computer simulation

军事上的紫外告警技术和紫外保密通信技术的需要已成为紫外传感技术发展的重要动力。本文通过采用国际上公认的大气传输特性模拟软件包 L OWTRAN,对由于地理位置、海拔高度、能见度、路径方向以及传输距离等几种因素变化的大气紫外传输特性进行了模拟分析。模拟结果不仅能够基本说明目前在国外紫外传感器技术应用中的一些结论 。

The military needs for ultraviolet alarming and ultraviolet secret communication is an important impulse for development of ultraviolet sensing technology.In this paper,by using the international atmospheric transmission simulation package LOWTRAN,the atmospheric ultraviolet transmission under varying conditions of geographical locations,heights above sea level,visibility,directions of light pathways and the transmission ranges are analyzed,and the simulation results thus obtained not only can basically exemplify some conclusions in current applications of UV sensing technologyies abroad,but also are useful in guiding the future research and development of UV sensing technology.
