We studied the diffraction halo function of partially coherent
speckle photography, using the theory of partial coherence of light and
speckle statistics. Numerical calculations were made on the basis
of the derived expression. It was shown that the anisotropic
coherence of the illumination induced by the source could lead to the
inhomogeneity of the halo distribution. An experiment was performed
to prove the theoretical predictions.
