Study of stokes polarimeters based on a single twisted nematic liquid crystal panel

In this work, we present the design, optimization and implementation of dynamic Stokes polarimeters based on a single Twisted Nematic Liquid Crystal (TN-LC) panel. TN-LC material enables both to introduce a retardance and to rotate the polarization ellipse orientation. For this reason, a simple setu...
