Equivalent Linearly Rotating Plates Constructed by Variable Plates
Variable retardation plates (VRP) were analyzed by quaternion theory and equivalent rotatable quarter-wave plates and rotatable half-wave plates were constructed from sequences of adjustable linear retarders with fixed retardation axes.To avoid reset,a polarization controller (PC) based on adjustable linear retarders using polarization controlling algorithm for rotatable plates was proposed and demonstrated.Simulation results show that the 4-plate polarization controller can transform any varying general input state of polarization (SOP) into an arbitrary linear output state of polarization,and the fluctuation of output light intensity is less than 1% while the rang of retardation is confined into 2π.This transformation is continuous,and reset-free and the phase shifts are smooth.
