大气紫外传输特性的计算机仿真分析

摘要

Military needs for ultraviolet alarming and ultraviolet security communication appear as important demands for the development of ultraviolet sensing technology. In this paper, adopting the international atmospheric transmission simulation package LOWTRAN, atmospheric ultraviolet transmission under varying conditions of geographical locations, altitude, visibility, directions of light pathways and the transmission ranges are analyzed. Simulation results thus obtained can basically explain some conclusions in current applications of UV sensing technology abroad, and are useful in guiding future research and development of UV sensing technology.%军事上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，本文通过采用国际公认的大气传输特性仿真软件包LOWTRAN，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仿真分析，仿真结果不仅能够基本说明目前国外紫外传感器技术应用中的一些结论，而且对于今后深入开展紫外传感技术的研究具有指导作用。
