The phase of optical wave can be recovered by the intensity transport equation under the paraxial approximation For the optical system with diffraction limit, it is difficult to get the boundary radical slope of phase and sample in the circular domain boundary when using the intensity transport equation to recover the phase, consequently, we reviewed an algorithm mentioned in the reference [4], namely, the equation, computation domain and boundary condition are changed, then the phase is reconstructed by the multigrid method and corrected at last Moreover, the experiment system is set to testify the algorithm, and the recovered phase from the intensity data detected by CCD is compared with the result from phase retrieval algorithm, it is found that the phase reconstruction error can reach 017 λ in the case of non-uniform intensity distribution, as a result, the method is suitable for the phase recovery with low wavefront sensing accuracy.
在傍轴近似条件下,可以利用光强传播方程对畸变波前进行相位恢复。对于衍射受限的光学系统,很难获得相位的边界径向斜率值作为边界条件,此外,要获得精确的圆域边界采样值也并非易事。为了克服上述困难,进一步研究了相位恢复改进方法,即改变了方程的表示形式、计算区域和边界条件,并用多重网格法进行求解获得重构相位,最后再将其修正。为了验证算法的精确性,搭建了实验系统对算法进行实验验证,将由CCD探测的光强分布进行计算得到的相位分布与相位恢复算法的结果进行比较,证明在光强分布非均匀的情况下,该方法恢复的相位均方根误差能够达到017 λ,可以适用于波前传感精度要求不是很高的相位恢复。标签自适应光学相位恢复相位修正光强传播方程 adaptive optics phase retrieval phase correction intensity transport equation
