| 摘 要： | 大气分子等粒子的存在对光的空间传播通常会产生光束的扩展、漂移等的影响.文中在随机媒质中光的传播理论的基础上,分析了构造大气湍流随机相位屏所需要的条件,采用McGlamery算法和Huygens-Fresnel原理,数值模拟给出了Kolmogorov谱下的大气湍流随机相位屏.分析了光波从发射机经湍流大气传播到达接收机平面时的光场变化特征.模拟分析表明:大气分子等粒子的存在,对光的振幅及能量的空间分布均造成很大的影响.

| Abstract: | The existence of atmospheric molecules and other particles usually affects the propagation of light through the atmospheric tubulence.In the paper,based on the theory of the light propagation through a random media,an analysis was made of the tectonic condition of the atmospheric tubulent phase screen,which was numerically simulated by using the McGlamery algorithm and the Huygens-Fresnel priciple.Then the far-field characteristic of the light beam propagating through the atmospheric tubulence from the transimitler plane to the receiver plane was also analyzed.The simulative study shows the existence of atmospheric molecules and other particles has a great impact on the energy distributions and amplitude of the light beam. |
