Abstract

The paper presents principal approaches to diagnosing the structure forming skeleton of the complex optical field. An analysis of optical field singularity algorithms depending on intensity discretization and image resolution has been carried out. An optimal approach is chosen, which allows to bring much closer the solution of the phase problem of localization of speckle-field special points. A possible approach to diagnosing the signs of zero amplitudes has been offered.
