Abstract

We present the analysis and implementation of a set of experimental procedures to characterize optical polarization properties as a function of the applied voltage for liquid-crystal variable retarders (LCVRs) in the transmission mode. The studied properties are those involved in the operation of the LCVRs and, generally, are the most significant for optical applications: retardance, diattenuation, optical axes position, and output depolarization effects. The correct characterization of these polarization properties can be useful to improve results or estimate errors in applications using these devices. The results obtained show good accuracy and good agreement with the expected results.
