我们提出了一种消偏器的基础上收集的半波片与随机分布的光轴的原则。该设计通过将液晶动态图案化成随机排列的均匀畴来演示。我们表征了1550 nm和C波段（1520-1610 nm）的液晶消偏器。对于任何线偏振光，都可以获得小于5%的偏振度。该研究为高性能消偏器的研制提供了一种实用的候选材料。
We propose a depolarizer based on the principle of a collection of half-wave plates with randomly distributed optic axes. The design is demonstrated by means of dynamically photopatterning liquid crystal into randomly aligned homogeneous domains. We characterize the liquid crystal depolarizer for 1550 nm and C-band (1520–1610 nm). A degree of polarization of less than 5% is obtained for any linearly polarized light. This study provides a practical candidate for high-performance depolarizers.
