激光辐照远场能流分布估算方法研究

Research on Evaluation Method of Remote Fluence Distribution of Laser Irradiation

激光与探测器的相互作用,可造成探测器光敏元能流密度超出饱和阈值.在分析了大气对激光传输的影响后,分水平传输和斜程传输2种情况下远场激光能量分布进行了理论估算,并给出了远场激光辐照效果的量化仿真估算.

The action between laser and detector will make the fluence density on the photosenstive area of the detecto higher than its saturation threshold. At first, the influence on the laser transportation induced by atmosphere is analyzed. Then the theoretic energy distribution of laser beam after remote distance transportation is also estimated under the horizontal and cater-corner transportation. At last, the remote irradiation effect is evaluated.
