摘要

微镜阵列可以用来校正由于大气湍流引起的波前像差。提出了一种简单的方法来估计矫正视力所需的纯活塞微镜的数量。我们还计算了需要多少个活塞尖端倾斜微镜。三致动器微镜被发现产生一个更有效的解决方案，需要减少4倍的致动器来实现相同的斯特雷氏比改进。

Turbulence compensation using micromirror arrays: the array design

An array of micromirrors can be used to correct the wavefront aberrations due to atmospheric turbulence. A simple method is presented for estimating the number of piston-only micromirrors needed to correct the seeing. We also compute how many piston-tip-tilt micromirrors are required. The three-actuator micromirrors are found to produce a more efficient solution, requiring 4X fewer actuators for the same improvement in the Strehl ratio.
