Abstract:

The ray approximation is constructed for the solution of the equation for the second–order coherence function. Based on the solution obtained in this approximation the self–actions are compared of coherent and partially coherent beams with equal Fresnel's numbers. The relation of this approximation with the ray approximations constructed for the solution of the small–angle radiative transfer equation is discussed.
