研究了一种聚合物稳定的蓝相液晶（BPLC）的电场诱导双折射。在低场区，传统的克尔效应成立。随着电场的增加，诱导双折射逐渐饱和，偏离克尔效应。提出了一种指数收敛模型，称为扩展克尔效应，以拟合实验数据。实验结果与模型吻合较好。这种扩展的克尔效应将对新兴的BPLC显示器件的优化产生重大影响。
Electric-field-induced birefringence of a polymer-stabilized blue-phase liquid crystal (BPLC) is investigated. In the low field region, conventional Kerr effect holds. As the electric field increases, the induced birefringence gradually saturates and deviates from Kerr effect. An exponential convergence model, called extended Kerr effect, is proposed to fit the experimental data. Good agreement between experiment and model is obtained. This extended Kerr effect will make a significant impact to the optimization of emerging BPLC display devices.
