Characteristics of scalar random field and its vortex networks. Recovery of the optical phase

Abstract

Some physical aspects of the role of vortices (and their networks) in the formation of a statistical field transporting the information about the initial image are considered. The results of field reconstruction of the object image by different chosen reconstruction samples formed under the use of field vortex characteristics are presented. The connection between the vortex network and the network of stationary points of intensity is considered. It is stated that most of the current gradient lines of intensity with their origin in saddle points are positioned in the areas where phase changes quickly. The results of computer simulation are presented.
