Numerical calculation of the propagation of spatial coherence from partially coherent sources
Abstract
This report considers the numerical calculation of the mutual intensity function of highly coherent laser radiation after reflection from a surface having roughness on the scale of the laser wavelength and at arbitrary distances from the reflector. The mutual intensity function characterizes the second-order spatial coherence properties of the nearly monochromatic reflected field and is of interest for evaluating the potential of coherent detection schemes for optical fuzing systems.
