One-time measurement to characterize complex amplitude single component in symmetry superposed optical vortices
Chen Wang, Yuan Ren
Complex amplitude measurement is an essential prerequisite for light field characterization. In this work, we propose a one-time measurement method to characterize the complex ampl…

Directly measuring mode purity of single component in superposed optical vortices
Chen Wang, Yuan Ren
Mode purity is an important reference for the quality of the optical vortex. In this work, we propose a self-interference method to directly measure single component in superposed…

Measurement and Shaping of Perfect Optical Vortex via Cross Phase
Chen Wang, Yuan Ren
We investigate a method for the measurement and shaping of a perfect optical vortex (POV) by using the cross-phase for the first time. Experimentally, we propose a method to measur…
