Abstract

We present a technique for controlling a ground-based deformable mirror adaptive optics telescope to compensate for optical wave-front phase distortion induced by a turbulent atmosphere. Specifically, a predictive linear quadratic Gaussian (LQG) controller is designed that generates commanded control voltages to the mirror actuators based on a set of time-delayed wave-front slope measurements from a Hartmann-type wave-front sensor.

摘要

我们提出了一种用于控制地基自适应光学望远镜中可变形镜的技术，以补偿由湍流大气引起的光波前相位畸变。具体而言，设计了一种预测线性二次高斯（LQG）控制器，该控制器基于来自哈特曼型波前传感器的一组时延波前斜率测量值，生成发送至镜致动器的指令控制电压。
