Abstract:

Based on analytical relations obtained for reconstructing the wave phase from the distribution of wave intensity, the peculiarities of the two-dimensional wave-front structure formation have been investigated, which are connected with interference zeros of the field. The presence of field zeros is shown to be insufficient for the existence of dislocations. The transition from the parabolic wave equation to the nonlinear integro-differential equation for the field intensity has been made for the first time.
