Abstract

In an interferometer based on optical vortices there are generated regular net of phase singularities. There are two kinds of optical vortex named positive and negative. The sign of the vortex is often named a topological charge of the optical vortex because its existence is related to the characteristic of the geometric wavefront. The ability to determine the sign of the optical vortices in the experimental measurements may be used to reconstruct the wavefront. In this paper authors present the experimental method to determine the sign of the optical vortices.
