我们介绍了一种新的成像技术，采用远程聚焦来解决液晶指向矢场中的轴向动力学问题。我们的方法的高轴向时间分辨率通过直接成像初始张开的向列层在突然电压脉冲作用下的指向矢场的演化来证明。给出了开关动力学的图像，揭示了液晶层的暂态指向矢组态和拓扑变化。
We introduce a novel imaging technique adopting remote focusing for resolving the axial dynamics in the director field for liquid crystals. The high axial time resolution of our approach is demonstrated by imaging directly the evolution of the director field for an initially splayed nematic layer subject to a sudden voltage pulse. Images of the switching dynamics are presented, revealing transient state director configurations and changes in topology of the liquid crystal layer.
