摘要:
根据电磁高斯-谢尔模型(EGSM)光束在湍流大气中传输时偏振特性的理论模型,研究EGSM光束在湍流介质中传输时整个光场的偏振特性.考察光源的偏振度、光源平面x,y两个方向的相干长度,以及光斑大小对光束偏振特性的影响.研究结果表明,部分相干光在湍流介质中传输时,偏振特性不仅会随着传输距离的增加而变化,而且在同一观察面内(z固定),偏振度也随位置的不同而不同.
Abstract:
Based on the theoretical model of partially coherent electromagnetic beams propagating in a turbulent atmosphere,the polarization property for a Gaussian-Schell model beam in the turbulent atmosphere has been investigated.The influence of polarization state,the spatial coherent length and the beam spot size of the source on the polarization properties have been discussed.It is found that the change of polarization not only varies with the propagation distance,but also varies with the radius in a transverse plane.
