论文摘要
巨大的可调光学组件是基于入射波前的动态重新配置（例如梁转向和可调镜头）实现的。然而，当前波前重新配置技术的主要范式依赖于比输出波前大得多的复杂控制系统，例如基于空间光调节器或相分阵列天线的横梁转向。在这里，我们提出了一个新的范式，用于使用具有相同自由度的控制系统对任意输出波动的动态重新配置。例如，使用半频线横梁转向的跨面二倍表的平面内两级（2DOF）机械启动系统证明了波前变压器，该系统测量了6-kHz调制速度和“+-65.6度”视野。该范式可用于与任何控制系统的动态波前变压器，以用于庞大的应用系统，例如可调透镜，梁转向和动态束探测器，仅举几例。
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.
