摘要

本文将传统的模态波前重建与压缩波前传感进行比较，利用Shack-Hartmann波前传感器重建自由曲面轮廓。模态波前重构表示Zernike域中的相位或波前。基于稀疏泽尼克表示(SPARZER)的压缩波前感知方法表示泽尼克域中的相位斜率。研究了压缩波前传感在自由曲面轮廓测量中的有效性。

Investigation on compressed wavefront sensing in freeform surface measurements

In this paper, conventional modal wavefront reconstruction is compared with compressed wavefront sensing to reconstruct freeform surface profiles using the Shack-Hartmann wavefront sensor. The modal wavefront reconstruction represents the phase or the wavefront in the Zernike domain. The compressed wavefront sensing method based on the sparse Zernike representation (SPARZER) represents the phase slopes in the Zernike domain. The effectiveness of compressed wavefront sensing in freeform surface profile measurements is investigated.
