Detection of dislocations as branching points of interference pattern

Abstract

In the present article the problem of Gaussian beam propagation in the turbulent atmosphere is considered on the base of numeric methods. Singular points (dislocations) development in the wavefront is analyzed. Two algorithms of dislocation detection were proposed. One of them based on the interferogramm processing and can be realized in a laboratory experiment. In the second algorithm the whole wavefront is analyzed and dislocations are localized as points where cutes of the surface in 2π begin. The precision of the algorithms is compared and statistics of dislocations on the path of propagation is represented.
