Abstract

As applied to various applied problems, a group of questions on optimizing the characteristics of vortex light beams used in multiplex optical systems is considered. A new method is proposed for the formation of systems of singular beams with small-scale dislocations, which provide a high degree of stability of their structure to the influence of diffraction effects.
