We report a rapid nano-imprinting technique to pattern the liquid crystal alignment of a Pancharatnam-Berry phase microlens array. Through implementing a single-side aligned cell, we demonstrate a switchable microlens array with fast response time and low operation voltage. Further investigation of focusing property as well as imaging capability ensure the good quality of the microlens array. Besides planar structures, this method is also promising for patterning liquid crystal alignment on curvilinear surfaces.
我们报告了一种快速的纳米压印技术，用于图案化潘查拉特纳姆-贝里相位微透镜阵列的液晶排列。通过实施单面对准单元，我们展示了一种具有快速响应时间和低操作电压的可切换微透镜阵列。对聚焦性能和成像能力的进一步研究确保了微透镜阵列的良好质量。除了平面结构外，这种方法在曲面上对液晶排列进行图案化也很有前途。
