Experimental results are presented related to the dynamic behaviour of Polymer Stabilized Ferro-electric Liquid Crystal (PSFLC) samples under external applied electric field, using Snap-shot Mueller Matrix Polarimetry (SMMP) and Mueller Matrix (MM) formalism. Different polarimetric coefficients are simultaneously extracted from each channeled spectrum measured with this full-optical SMMP technique. The impact of the concentration of polymer present into the liquid crystal cell on this dynamic behaviour is studied, permitting a direct and quick characterisation of the material. The results obtained for PSFLC are compared with those already measured for pure Surface Stabilized Ferro-electric Liquid Crystal (SSFLC) samples, which correspond to a 0% concentration in polymer.
本文展示了利用快照穆勒矩阵偏振测量法（SMMP）和穆勒矩阵（MM）形式体系，研究聚合物稳定铁电液晶（PSFLC）样品在外部施加电场下的动态行为的实验结果。使用这种全光学SMMP技术，从每个通道光谱中同时提取不同的偏振系数。研究了液晶盒中聚合物浓度对这种动态行为的影响，从而可以直接快速地表征该材料。将PSFLC获得的结果与已测量的纯表面稳定铁电液晶（SSFLC）样品的结果进行比较，后者对应聚合物浓度为0%。
