一,引言激光由于它具有独特的辐射特性,自六十年代发明以来,已在通讯、测距、雷达、制导、光武器、红外遥感以及大气污染监测等各种长距离应用方面展现出广阔的前景。但在实际应用中,与相应的红外工程一样,均受到大气条件的影响;特别是浓雾,对激光辐射传输有很大威胁。激光在浓雾中的传输规律如何,以及是否存在有效窗口等问题急待解决。
I. INTRODUCTION Because of its unique radiation characteristic, laser has been widely used in various long distance applications such as communication, ranging, radar, guidance, light weapons, infrared remote sensing and air pollution monitoring since it was invented in the 1960s prospect. However, in actual application, as with the corresponding infrared project, it is affected by the atmospheric conditions; in particular, dense fog poses a great threat to laser radiation transmission. Laser transmission in dense fog how, and the existence of effective windows and other issues urgently need to be resolved.
