Wave front dislocations generated by the vortex flow of the light energy in vicinity of the points where the field intensity equals zero are studied on the basis of obtained relation between the phase and intensity in optical beam (the phase problem solution). Reasons of an ambiguity of the phase problem solution are discussed. An analytic formula for retrieving the potential phase from the known intensity distribution has been obtained. A possibility to use an information on the potential phase for correction of singular phase distortions by the optical adaptive systems is discussed.
