Optimized Stokes polarimeters based on a single twisted nematic liquid-crystal device for the minimization of noise propagation

This work evidences the suitability of applying a single twisted nematic liquid-crystal (TN-LC) device to obtain dynamic polarimeters with high accuracy and repeatability. Different Stokes polarimeter setups based on a TN-LC device are optimized, leading to the minimization of the noise propagated f...
