An iterative wavefront reconstruction method using Shack–Hartmann wavefront sensor (SHWFS) measurements is presented in this paper. A new cost function for the wavefront reconstruction problem is derived and the solution is obtained iteratively using the gradient descent method. The proposed method aims to effectively handle the scintillated SHWFS measurements and to provide simpler and accurate ways to achieve branch-point-tolerant wavefront reconstruction suitable for adaptive optics compensation of strong turbulence. Simulated iterative wavefront reconstruction results show the effectiveness of the proposed method. A laboratory optical testbed is also presented to show the experimental implementation of the proposed method.

使用Shack–Hartmann波前传感器测量，对强湍流进行迭代波前重构

本文提出了一种使用Shack-Hartmann波前传感器（SHWFS）测量的迭代波前重建方法。推导了一种新的波前重建问题代价函数，并采用梯度下降法迭代求解。所提出的方法旨在有效处理闪烁的SHWFS测量值，并提供更简单准确的方法来实现适合于强湍流的自适应光学补偿的耐分支点波前重建。仿真的迭代波前重建结果表明了该方法的有效性。还提供了一个实验室光学测试台，以展示该方法的实验实现。
