Abstract

The construction process and characteristics of a deformable mirror eigenmode are introduced. The eigenmode of a 37-element micromachined membrane deformable mirror (MMDM) from OKO, Ltd. is analyzed. The Gaussian-Seidel low-order aberrations are fitted with eigenmodes as basic functions. An experimental adaptive optics (AO) system is constructed with the MMDM as the wavefront corrector, a deformable mirror eigenmode as the wavefront control algorithm, and a Shack-Hartmann wavefront sensor as the wavefront detector. The experimental results demonstrate that the deformable mirror eigenmode can act as the wavefront control algorithm for the AO system based on the MMDM.

摘要

介绍了变形镜本征模的构建过程及特性。分析了OKO有限公司的37单元微机械薄膜变形镜（MMDM）的本征模。以本征模为基本函数拟合高斯-赛德尔低阶像差。构建了一个实验性自适应光学（AO）系统，该系统以MMDM作为波前校正器，以变形镜本征模作为波前控制算法，以夏克-哈特曼波前传感器作为波前探测器。实验结果表明，变形镜本征模可作为基于MMDM的AO系统的波前控制算法。
