Analogue of the van Cittert-Zernike theorem for statistically homogeneous wave fields.
A theorem is presented that expresses a correspondence between the degree of spatial coherence of statistically homogeneous fields and the complex amplitude in certain monochromatic fields. The theorem is illustrated by an example that shows the behavior of the degree of spatial coherence of certain partially coherent fields throughout a three-dimensional volume region.
