Paper Abstract

The regularities of spatial distribution of amplitude nulls of the visibility complex function and areas of branching the low-frequency interference fringes in two relative displaced identical fields superposition are considered. The character of the spatial distribution of the null visibility surfaces in the volume of the superposition speckle field has been investigated by the stationary phase method. It is shown that in the character transverse and longitudinal sections of the superposition field the phase deviation and the interference fringe branching have an effect differently depending on the shape of aperture limiting the input pupil of the imaging system. The results of the experiments have shown good correspondence with the conclusions of the theory.
