We present a theory for Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts for beams of light with arbitrary spatial coherence. By applying the well-known theory of partial spatial coherence, we can calculate explicitly spatial and angular GH and IF shifts for completely polarized beams of any shape and spatial coherence. For the specific case of a Gauss-Schell source, we find that only the angular part of GH and IF shifts is affected by the spatial coherence of the beam. A physical explanation of our results is given.
我们提出了一种针对任意空间相干性的光束古斯-汉欣（GH）和因伯-费多洛夫（IF）位移的理论。通过应用部分空间相干性的著名理论，我们可以明确计算出任何形状和空间相干性的完全偏振光束的空间和角度 GH 和 IF 位移。对于高斯-谢尔源的具体情况，我们发现只有 GH 和 IF 位移的角度部分受到光束空间相干性的影响。我们给出了对结果的物理解释。
