Abstract

Effective control of large-aperture tip-tilt mirrors (TTMs) has been a pressing concern in beam stabilization due to the influence of their internal mechanical resonance. To the best of our knowledge, this Letter reports a new high-efficiency actor-critic (HEAC) scheme to effectively eliminate the impact of mechanical resonance on jitter suppression stabilization and performance. Moreover, HEAC features rapid deployment and training that rely solely on online noisy measurements through the establishment of a specific tracking control problem, the decoupling of the unknown system parameters, and the design of a quadratic homogeneous polynomial basis function network. The experimental results demonstrate that the HEAC has successfully achieved stable and efficient suppression of jitter near the resonance peak or close to the Nyquist frequency for a

具有不可忽略共振的大口径倾斜反射镜的光束抖动抑制方法

由于大口径倾斜反射镜内部机械共振的影响，对其进行有效控制一直是光束稳定研究中一个迫切需要解决的问题。据我们所知，本文报告了一种新的高效actor-critic （HEAC）方案，可以有效地消除机械共振对抖动抑制、稳定和性能的影响。此外，通过建立特定的跟踪控制问题、解耦未知系统参数和设计二次齐次多项式基函数网络，HEAC具有快速部署和训练的特点，仅依赖在线噪声测量。实验结果表明，对于$\Phi ~405$ mm孔径的TTM， HEAC成功地稳定有效地抑制了谐振峰附近或奈奎斯特频率附近的抖动。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
