| 摘 要： | 降雨会对激光信号产生严重的衰减,从而给激光目标探测的应用带来一定影响.激光在降雨中的传输衰减已在红外波段做了大量的实验研究,而可见光波段激光在雨中的传输衰减特性还未见报道.基于夫琅禾费衍射和几何光学散射理论,建立雨滴对532 nm绿激光和1064 nm近红外激光光束的传输衰减模型,对比分析两波长激光在不同降雨量下的衰减...

| Abstract: | Rainfall can bring serious attenuation to the laser signals,so it will take some influence to the laser detection system applied in the rain.The attenuation of laser beam propagating in the rain is lucubrated in the infrared range,but the attenuation of green laser in the rain has not been reported.Therefore,based on Fraunhofer diffraction and geometric optics theory,the attenuation model of laser radiation at 532 nm and 1064 nm by raindrops is founded,and the attenuation characteristics are contrasted and ... |
