在过去的几年中，一类随机电磁光束（所谓的电磁高斯谢尔模型光束），在自由空间中传播的偏振态的变化进行了研究。在本文中，我们将分析扩展到均匀，各向同性，非吸收大气湍流中的传输。我们发现，湍流对偏振态的影响是最显着的，当大气波动是弱或中等，而在一个强的制度的大气波动的光束的偏振态返回到其原始状态。我们的研究结果可能会在通过大气进行传感，成像和通信方面找到有用的应用。
During the last few years, changes in the state of polarization of a class of random electromagnetic beams (so-called electromagnetic Gaussian Schell-model beams), propagating in free space have been investigated. In the present paper, we extend the analysis to propagation of such beams in homogeneous, isotropic, non-absorbing atmospheric turbulence. We find that the effects of turbulence on the state of polarization are most significant when the atmospheric fluctuations are weak or moderate, whereas in a strong regime of atmospheric fluctuations the state of polarization of the beam returns to its original state. Our results might find possible useful applications for sensing, imaging and communication through the atmosphere.
