阅读说明：本技术 可切换宽带波片 (Switchable broadband wave plate ) 是由 雅克·戈利耶 吕璐 彭枫琳 于 2020-03-24 设计创作，主要内容包括：提供了一种光学波片。光学波片包括堆叠在一起的多个液晶(“LC”)层。多个LC层中的至少一个LC层包括LC分子,该LC分子能够通过外部场进行平面内切换,以在具有不同相位延迟的状态之间切换光学波片。(An optical waveplate is provided. Optical waveplates include multiple liquid crystal ("LC") layers stacked together. At least one of the plurality of LC layers includes LC molecules that are capable of in-plane switching by an external field to switch the optical waveplate between states having different phase retardations.)
