Galushko Y. Singularities networks of the scalar optical fields

The influence of single vortex on the scalar field is considered. It is shown that such influence is expanded, at least, on the half of the correlation length. It is shown that original image may be restored by the Shennon sample, which is formed on the base of analysis vortex network. The results of the original image restoration are presented. It is shown that averaged squared gradient of phase in the intensity saddle point is more on 2 times then one at any other point of a field. Similarlysituation is observed, in the phase saddle points. The vortices of different signs are connected by the current intensity gradient line crossed the intensity saddle point. The new method of vortex identification based on the shift interferometry is elaborated.
