Zusammenfassung
In this work we present different aspects that we have to manage when we want to evaluate the retardance introduced by a variable waveplate, or any device that behaves in that way. In our experience, and due to the trigonometric functions that are involved, we have find that we always appears some uncertainty in the measured retardance that are limited by the values obtained by the used trigonometric functions. We will try to contextualizethe results with the different methods of unwrapping that we can use and at what point the wrapping occurs. We will make some considerations to consider making the evaluated retardance closer to the real retardance introduced by the waveplate.
