Paper Abstract

The regular net of optical vortices can be generated by three plane wave interference. Such regular vortices are used in a new kind of interferometry—optical vortex interferometry. In this work, the experimental method for topological charge determination of optical vortices in a regular net is presented. This allows for unique phase reconstruction in optical vortex interferometry and solves what is known in interferometry as the phase unwrapping problem.
