我们提出了第一个实验验证的振动滤波与线性二次高斯（LQG）控制律的自适应光学（AO）。一个准纯机械振动产生的经典AO工作台和过滤的控制律，导致斯特列尔比和图像稳定性的改善。振动滤波可应用于任何AO系统，但这些结果对于eXtrem AO特别重要，例如对于要求高性能的SPHERE AO设计。
We present a first experimental validation of vibration filtering with a Linear Quadratic Gaussian (LQG) control law in Adaptive Optics (AO). A quasi-pure mechanical vibration is generated on a classic AO bench and filtered by the control law, leading to an improvement of the Strehl Ratio and image stability. Vibration filtering may be applied to any AO system, but these results are of particular interest for eXtrem AO, and for instance for the SPHERE AO design, where high performance is required.
