在复杂的ABCD矩阵理论的框架内发现了由随机各向异性相位屏调制的电磁束穿过任何光学系统时相干性和偏振的变化。这意味着该形式可以处理成像和傅里叶变换和自由空间光学系统，以及具有高斯传输形状的有限尺寸限制孔径的分数傅里叶变换系统。因此，本文应被视为 Shirai 和 Wolf [J.选择。苏克。是。 A21，1907（2004）]。将表明，光学系统中孔径的包含不仅强烈影响空间相干性的传播，而且强烈影响传播场的偏振度。相干性和偏振传播的解析表达式将根据任何复杂光学系统的矩阵元素给出。
The change of coherence and polarization of an electromagnetic beam modulated by a random anisotropic phase screen passing through any optical system is found within the framework of complex ABCD-matrix theory This means that the formalism can treat imaging and Fourier transform and free-space optical systems, as well as fractional Fourier transform systems, with finite-size limiting apertures of Gaussian transmission shape. Thus, the current paper shall be considered as a continuation, extension, and generalization of a previous work by Shirai and Wolf [J. Opt. Soc. Am. A21, 1907 (2004)]. It will be shown that the inclusion of apertures in the optical system strongly influences not only the propagation of spatial coherence but also the degree of polarization of a propagating field. Analytical expressions of coherence and polarization propagation will be given in terms of the matrix elements for any complex optical system.
