Peculiarities of statistical distribution of the phase difference in the speckle-field: the numerical simulation and natural experiment

With help of the numerical statistical experiment it is shown that the phase difference between two points of speckle fields in the far-field diffraction can be taken with most probability to be the values 0 and p radian. With the help of numerical simulations and natural experiment with using Young's interferometer histograms of statistical distribution of the phase difference between two points of speckle field are obtained. The results of numerical experiments are coincided with the results of the natural experiments and theoretical concepts.
