我们将van Cittert-Zernike定理推广到具有部分极化的空间非相干源。我们通过一个简单的例子说明，由这些源生成的字段可以拥有具有有趣属性的相关矩阵。特别地，我们证明了通过在非相干源上适当调制偏振态，场的正交分量之间的相关性以及偏振度在传播过程中可能会发生巨大的变化。
We introduce an extension of the van Cittert-Zernike theorem to spatially incoherent sources with partial polarization. We show through a simple example that fields generated by such sources can possess correlation matrices with interesting properties. In particular, we show that by suitable modulation of the polarization state across the incoherent source, the correlation between the orthogonal components of the field as well as the degree of polarization may drastically change on propagation.
