摘要
从推广的Huygens Fresnel原理出发,对在随机介质中传输的部分相干光偏振态的演化作了研究。以偏振高斯 谢尔模(PGSM)光束为例,进行了理论计算。结果表明:由于随机扰动的影响,偏振度呈现出振荡变化,并且光源的空间相干性对振荡剧烈程度有着很大的影响。
By the extended Huygens-Fresnel principle,the change of polarization state of partially coherent light propagated in random media was studied.As an example,partially polarized Gaussian-Schell model(PGSM) beam was analyzed in detail.The results show that degree of polarization of a PGSM beam will oscillate because of the influence of random turbulence.The spatial coherence of a PGSM source has a strong influence on the oscillation of degree of polarization.
