Abstract:
The method of vortex topological charge detection based on measurements of light field intensity and design of a corresponding detector are suggested. A mathematical model of the detector is introduced in the work. Results of numerical experiments simulating recognition of a vortex in the presence of noise are also presented along with assessments of the detector performance. The data of numerical experiments are confirmed by analytical calculations.
