Polarization measurement of electronically controlled vector vortex light
In order to study the influence of electrically controlled phase delay on the polarization state of vector vortices, a full Stokes polarization measurement for electrically controlled polarization vortexing was built by using a liquid crystal variable retarder and a liquid crystal q wave-plate. Muller matrix analysis and experimental verification of Stokes parameter transmission characteristics of electronically controlled vector vortices were presented. By continuous phase control of the input polarized light, the polarization regulation evolution of the output light beam was obtained after it passes through the tuned q wave-plate. The results show that the electrically controlled phase delay can change the ellipsicity of the local polarization of the angular and radial polarized light, and the change of the polarization state can affect the output intensity of the vector vortex light. The research is of great significance to the exploration of polarization conversion of electrically controlled vector vortices.
