Polarization Measurement Using Vortex Beams With Non-Integer Orbital Angular Momentum

Polarization measurement has been used for many optical applications in science and technology. Herein, we adopt a reliable method to measure the polarization parameters of incident light, including principal axis, chirality ellipticity based on superposition two orthogonal vortex beams with non-integer topological charges (TCs). All three can be measured analyzed by interference pattern produced ${\ell }_1 = 1$ }_2{\rm{ 0}}{\rm{.5}}$ . The relationship between axis is deduced theoretically. results agree theoretical formulation very well. advantages simplicity make this have good application prospect measurement, communication, micro-particles manipulation quantum science.
