Abstract :
The method is proposed of optical vortex topological charge detection along with a design of a corresponding detector. The developed technique is based on measurements of light field intensity. Mathematical model simulating performance of the detector is described in the paper and results of numerical experiments are presented which illustrate recognition of a vortex in the presence of amplitude and phase noise in the registered radiation.
