Paper Abstract

The connection between vortex network and network of stationary points of intensity is considered. It is stated that most of current gradient lines of intensity with the origin in saddle points are positioned in the areas where phase changes quickly. The results of computer simulation are presented. The technique for determining the vortex sign in the scalar fields (including the statistical ones) under conditions when the use of the regular reference beam is impossible is described. The elaborated approach is based on the shift-interferometry technique. The conditions of the optimal vortices identification are formulated. The results of the computer simulation and experimental confirmation are presented.
