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 interferogram 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 cuts of the surface in 2(pi) begin. The precision of the algorithms is compared and statistics of dislocations on the path of propagation is represented.
