Abstract: The statistics of the formation of local intensity maxima in the focal plane of a converging lens after the Gaussian beam passes the spiral phase transparency in the presence of amplitude-phase noise in the beam is numerically studied. It is shown that, at the field fluctuation amplitude of about 15

Keywords: optical vortex, amplitude-phase noise.
