摘要
从推广的惠更斯-菲涅尔原理出发,推导出了电磁光束的偏振态在湍流介质中传输的表达式。并以电磁厄米-高斯模型光束为例,研究了湍流对电磁厄米-高斯模型光束偏振态的影响。进一步采用ITU-R在2001年提出的随高度变化的大气结构常数模型,研究斜程湍流大气中激光波束偏振传输特性。
According to extended Huygens-Fresnel principle and unified theory for polarization and coherent, the degree of polarization expression for laser beam was deduced. With this expression, the variation rule for degree of polarization in ease of 1550nm and 850hm Laser in slant path atmosphere was obtained.
