Spatial coherence of optical fields can be considered as beam structured if the size of the coherence patch varies slowly through the propagation of the optical field. As a consequence, the correlation of the optical field will be concentrated in a finite region around the direction of propagation. For properly describing it in the Fraunhofer-Fresnel domain, the marginal cross-spectral density is introduced. The superposition of spatial coherence beams in this domain is also analysed. It produces an interference field and a spatial coherence Moiré.

Keywords: Cross-spectral density; Moiré pattern; Young's interference; Zernike's formula
