Abstract

A method for determining the topological charge of an optical vortex using off-axis parabolic mirror (OPM) is reported. The results of the diffraction patterns obtained in the reflected focal point of an OPM show the intensity pattern and its orientation depend on the charge of the vortex as well as its sign. The experimental results agree well with the simulation results. The capability and robustness of this method are demonstrated by the detection of the topological charge as high as ±250.
