6- kHz机械驱动光束转向的基于二自由度控制系统的动态波前Transformer
Dynamic wavefront transformer based on a two-degree-of-freedom control system for 6-kHz mechanically actuated beam steering
摘要：
基于入射波前的动态重构，可以实现大量的可调谐光学元件，如光束控制和可调谐透镜。然而，当前波前重构技术的主导范例依赖于具有比输出波前大得多的自由度的复杂控制系统，例如基于空间光调制器或相控阵天线的波束转向。在这里，我们提出了一个新的范例，任意输出波前使用控制系统具有相同的自由度的动态重构。作为一个例子，波前Transformer被证明使用面内两自由度（2DOF）的机械致动系统的超表面偶半全向波束转向，其测量6 kHz的调制速度和“± 65.6度”的视场。该范例可以应用于超颖表面Transformers，以用于具有用于大量应用的任何控制系统的动态波前重新配置，例如可调透镜、光束转向和动态光束轮廓仪，仅举几例。
英文摘要：
Vast tunable optical components are realized based on dynamic reconfigurations of the incident wavefronts, such as beam steering and tunable lens. However, the dominant paradigm of current wavefront reconfiguration technologies relies on complex control systems with degrees of freedom much larger than output wavefronts, e.g. beam steering based on spatial light modulator or phased array antennas. Here, we propose a new paradigm for dynamic reconfiguration of arbitrary output wavefronts using control systems with the same degrees of freedom. As an example, a wavefront transformer is demonstrated using an in-plane two-degree-of-freedom (2DOF) mechanical actuation system of metasurface doublet for semi-omnidirectional beam steering, which measured a 6-kHz modulation speed and a "+-65.6 degree" field of view. This paradigm can be applied to metasurface transformers for dynamic wavefront reconfiguration with any control system for vast applications, such as tunable lens, beam steering, and dynamic beam profiler, just to name a few.
