设计了一种微流控系统来制备形状、表面光洁度和尺寸可控的聚合物分散液晶微球。将单分散的微球组装成微透镜阵列。在MLA中，每个微球充当单独的成像单元。由于所使用的液晶是含有光响应性的4-丁基-4-甲氧基偶氮苯的混合液晶，MLA的成像能力和光传输可以通过光照射进行可逆控制。
A microfluidic system is designed to fabricate polymer dispersed liquid crystal microspheres, whose shape, surface smoothness, and size are controlled. A microlens array (MLA) is constructed by the assembly of the monodispersed microspheres. In the MLA, each microsphere acts as a separate imaging unit. As the liquid crystal (LC) used is a mixed liquid crystal that contain photoresponsive 4‐butyl‐4‐methoxyazobenzene, the imaging capability and light transportation of the MLA can be reversibly controlled by light irradiation.
