We derive a spectral interference law that governs the behavior of the four Stokes parameters in Young's two-pinhole experiment with a random electromagnetic beam. In addition to the visibility of intensity fringes, we introduce three new contrast parameters that describe the interference-induced changes in the field's state of partial polarization. The polarization modulation depends on the electric field correlations at the pinholes and is closely related to the two-point Stokes parameters. The results are expected to be particularly useful in polarization interferometry and electromagnetic coherence theory. The formalism is demonstrated with specific examples.
我们推导了一个光谱干涉定律，该定律适用于随机电磁光束在杨氏双针孔实验中四个斯托克斯参数的行为。除了强度条纹的可见度外，我们还引入了三个新的对比度参数，用于描述干涉引起的场部分偏振态的变化。偏振调制取决于针孔处的电场相关性，并且与两点斯托克斯参数密切相关。预计这些结果在偏振干涉测量和电磁相干理论中将特别有用。通过具体例子展示了该形式体系。
