We propose a method for the characterization of electromagnetic Gaussian Schell-model (EMGSM) beams. This method utilizes the first-order interference consisting of polarization-state projections along with the two-point (generalized) Stokes parameters. The second-order field correlations employed in this method enable us to determine both the magnitude and the argument of the complex degree of electromagnetic coherence. We experimentally demonstrate this method by characterizing an EMGSM beam, which is synthesized using a laser beam passing through a rotating ground glass diffuser. This beam-characterization method is expected to be potentially useful for probing the partially coherent and partially polarized beams, and have tremendous applications in broad areas of optical communication and beam propagation.

使用一阶干涉表征电磁高斯Schell模型光束。

我们提出了一种表征电磁高斯谢尔模型(EMGSM)光束的方法。该方法利用了由偏振态投影以及两点(广义)斯托克斯参数组成的一阶干扰。此方法中使用的二阶场相关使我们能够确定电磁相干复杂度的大小和参数。我们通过表征EMGSM光束来实验证明这种方法,该光束是通过穿过旋转毛玻璃扩散器的激光束合成的。该光束表征方法有望用于探测部分相干和部分偏振的光束,并且在光通信和光束传播的广泛领域中具有巨大的应用。
