WebIn our model, partially coherent light is approximated as a set of random or plane wavefronts passing through spatial bandpass filters, which corresponds to an illumination pupil, and each wave coherently propagates onto a sensor plane through object space. Webspatially incoherent optical solitons have attracted much attention. Until now, three approaches have been devel-oped to describe partially incoherent wave propagation in nonlinear media: (i) the propagation equation for the mutual coherence function [3], (ii) the coherent density method [4], and (iii) the self-consistent multimode theory [5].
