Cholesteric liquid crystal (CLC) chiral superstructures exhibit unique features; that is, polychromatic and spin‐determined phase modulation. Here, a concept for digitalized chiral superstructures is proposed, which further enables the arbitrary manipulation of reflective geometric phase and may significantly upgrade existing optical apparatus. By encoding a specifically designed binary pattern, an innovative CLC optical vortex (OV) processor is demonstrated. Up to 25 different OVs are extracted with equal efficiency over a wavelength range of 116 nm. The multiplexed OVs can be detected simultaneously without mode crosstalk or distortion, permitting a polychromatic, large‐capacity, and in situ method for parallel OV processing. Such complex but easily fabricated self‐assembled chiral superstructures exhibit versatile functionalities, and provide a satisfactory platform for OV manipulation and other cutting‐edge territories. This work is a vital step towards extending the fundamental understanding and fantastic applications of ordered soft matter.

自组装手性上层结构的数字化，用于光学涡旋处理

胆甾型液晶（CLC）手性超结构具有独特的功能。也就是说，多色和自旋确定的相位调制。在此，提出了一种用于数字化手性上层建筑的概念，该概念还使反射几何相位的任意操纵成为可能，并且可以显着升级现有的光学设备。通过编码专门设计的二进制模式，展示了一种创新的CLC光涡旋（OV）处理器。在116 nm的波长范围内，以相同的效率提取了多达25个不同的OV。可以同时检测多路复用的OV，而不会产生模式串扰或失真，从而允许采用多色，大容量和原位方法进行并行OV处理。这种复杂但易于制造的自组装手性上部结构具有多种功能，并为OV操作和其他前沿领域提供了令人满意的平台。这项工作是朝着扩展对有序软物质的基本理解和出色应用的重要一步。
