A focus-swing liquid-crystal (LC) microlens with two patterned electrodes and filled in nematic liquid crystal is proposed. In order to lower the level of the applied voltage signal and effectively increase the focus-swing range, the bottom electrode is designed as a circular patterned structure. The top electrode is composed of four stripe-patterned subelectrodes, which are powered, respectively to generate expecting potential and drive the focus swing in the focal plane of the microlens. The common optical properties of the LC microlens and the swing behavior of the formed focus in the focal plane are demonstrated experimentally.
提出了一种具有两个图案化电极并填充向列型液晶的聚焦摆动液晶（LC）微透镜。为了降低施加电压信号的电平并有效增加聚焦摆动范围，底部电极设计为圆形图案结构。顶部电极由四个条纹图案化的子电极组成，分别供电以产生预期电位并驱动微透镜焦平面中的焦点摆动。通过实验证明了LC微透镜的常见光学特性以及在焦平面中形成的焦点的摆动行为。
