摘要：

The present work presents, for the first time, the dynamic evolution of the hysteresis loops R(V), specifically based onto the total retardance polarimetric parameter R(t) extracted from the Mueller Matrix (MM) of Twisted Ferro-electric Liquid Crystal (TwFLC) samples. This evolution is given for increased exposure time T-exp to a rectangular periodic electric field E-app preliminary applied to the sample, before performing the polarimetric measurements. The Mueller Matrix formalism used is found as a relevant non-destructive and non invasive full-optical method to characterize and to monitor the Twisted Ferroelectric Liquid Crystal cell dynamic behaviour under external applied electric field, before reaching the so-called stripes regime.
