| 大气悬浮微粒对激光传输透过率的影响是激光应用中应考虑的重要问题。为了提高激光传输透过率，对悬浮微粒的特性进行了研究。以激光传输和微粒特性为基础，基于Mie散射理论，建立激光透过率模型，并编写了计算透过率的可视化界面。针对不同悬浮微粒特性对激光透过率的影响做了系统的仿真分析。结果表明：激光透过率具有波长依赖性；悬浮微粒种类具有明显的地域性；不同种类的微粒对激光透过率影响程度不同，不可溶性粒子的影响较大；折射率对激光透过率的影响因悬浮微粒种类不同而出现正相关或负相关；粗粒子模态对激光透过率的影响较为显著。 |

| The influence of atmospheric suspended particles on laser transmission is an important issue to be considered in the laser applications. In order to improve the laser transmission transmittance, the characteristics of suspended particles were studied. Based on the laser transmission, particle characteristics and Mie scattering theory, a laser transmittance model was established. And the visual interface for calculating the transmittance was compiled. The laser transmittance of different suspended particles’ characteristics was systematically simulated and analyzed. The simulation results showed that the laser transmittance was wavelength dependent. The types of suspended particles had obvious regional characteristics. Different kinds of particles had different effects on laser transmittance, among which insoluble particles had a great influence. The influence of refractive index on laser transmittance was positively or negatively correlated with the different particles. The coarse particle mode had a significant effect on the laser transmittance. |
