摘要：
The well-known model of a diffusely scattering surface as a set of randomly distributed point scatterers is generalized to the case of a volume diffuser. Assuming that the coordinates of the coherent radiation source, the observer, and also the diffuser shape are arbitrary, a formula is obtained for the spatial correlation function of the scattered radiation intensity in a free field. Expressions to determine the transverse and longitudinal dimensions of the speckles are obtained for diffusers in the form of a rectangular parallelepiped and a cylinder.
