提出了一种利用染料掺杂胆甾相液晶(CLC)的光诱导取向来制作可图案化微镜器件的简单方法。光激发吸附染料可以使CLC织构从随机分布变为近乎完美的平面。这种结构转换导致反射率显著增加。利用这种光图案化技术，还展示了用作光栅的一维和二维微镜阵列。
A simple method for fabricating patternable micro-mirror devices by photo-induced alignment of dye-doped cholesteric liquid crystal (CLC) is demonstrated. The CLC texture can be changed from random distribution to nearly perfect planar by the photo-excited adsorbed dyes. This structure transformation leads to a substantial reflectivity increase. Using this photo-patterning technique, one- and two-dimensional micro-mirror arrays which function as gratings are also demonstrated.
