变形镜振幅校正的迭代算法

Iteration Algorithm of Amplitude Correction Using Deformable Mirror

本文提出了一种变形镜用于振幅校正的“迭代算法”,只需一次迭代,就可得到比“小信号算法”高一倍的校正精度,可满足一般的振幅校正要求。这种算法还基本解决了Karr提出的有限孔径引起的截断误差问题。

An 'iteration algorithm' of amplitude correction using deformable mirrorwas given in this paper. If we iterated one time using this algorithm, a precision twiceas high as the 'small signal algorithm' could be attained. It also solved the problem oftruncation errors induced by limited aperture.
