| 摘 要： | 从部分相干光的传输理论出发,采用光束相干-偏振矩阵方法研究了被光阑衍射部分偏振高斯-谢尔模型光束的远场特性,对远场偏振和光强特性作了详细的数值计算和物理分析。研究结果表明,光阑衍射部分偏振高斯-谢尔模型光束的远场特性与光阑截断参量、光的空间相干性和衍射角有关。并与自由空间的传输特性和以前的工作作了比较分析。

| Abstract: | Based on the beam coherent-polarization matrix approach and propagation law of partially coherent beams,the propagation properties of partially polarized Gaussian Schell-model beams diffracted through an aperture in the far field are studied.Detailed numerical calculation results and physical analysis are presented and illustrated for the far-field polarization and intensity properties.It is shown that the far-field behavior of diffracted partially polarized Gaussian Schell-model beams depends on the truncation parameter,spatial coherence parameters and diffraction angle.The corresponding results for the unapertured case are given and a comparison with the previous results is also made. |
