我们考虑用相位恢复（PR）来校正光学系统中的相位像差。利用点扩散函数（PSF）的三个测量值来估计像差。对于每次测量，使用可变形镜（DM）应用不同的离焦像差。一旦使用PR算法估计了像差，我们使用DM进行像差校正，并使用Shack-Hartmann波前传感器测量剩余像差。扩展Nijboer-Zernike理论用于模拟PSF。PR问题是通过一种基于矩阵秩最小化的PhaseLift算法和另一种基于交替投影的算法来解决的。为了进行比较，我们包括使用经典PR算法获得的结果，该算法基于交替投影并使用快速傅里叶变换。(C) 2015美国光学学会
We consider using phase retrieval (PR) to correct phase aberrations in an optical system. Three measurements of the point-spread function (PSF) are collected to estimate an aberration. For each measurement, a different defocus aberration is applied with a deformable mirror (DM). Once the aberration is estimated using a PR algorithm, we apply the aberration correction with the DM, and measure the residual aberration using a Shack-Hartmann wavefront sensor. The extended Nijboer-Zernike theory is used for modelling the PSF. The PR problem is solved using both an algorithm called PhaseLift, which is based on matrix rank minimization, and another algorithm based on alternating projections. For comparison, we include the results achieved using a classical PR algorithm, which is based on alternating projections and uses the fast Fourier transform. (C) 2015 Optical Society of America
