Abstract
By analysis of the degree of cross-polarization of a stochastic electromagnetic vortex beam, we find that the number of bright ring dislocations is equal to the topological charge of the vortex beam. Based on this property, we suggest a method to access the measurement of the orbital angular momentum of vector vortex beams, which holds true for cases of high coherence or low coherence.
