Feasibility of noninterferometric techniques of the phase distribution measurements in the laser beam cross-section for visualization of the vortex dislocations of optical speckle-field wave fronts are analyzed. It has been established that the diffraction Hartmann sensor and wave front sensor based on measurements of the intensity in the beam cross-section allow the positions of the dislocation centers to be obtained and spatial configuration of the intensity zero-lines to be retrieved.
