Alternative techniques for measuring the topological charge in optical vortices

A set of alternative methods to measure the topological charge of optical vortices is presented. The first method uses a displaced superposition of two beams with orthogonal polarization states in a Cartesian basis (horizontal and vertical), while the second method uses a superposition of auxiliary...
