We validate the quantitative analysis of Ronchigrams for wavefront sensing through detailed numerical simulations. Analysis of the experimental Ronchigrams provides the wavefront aberrations, the F/# of the beam and the distance of the Ronchi ruling from the paraxial focus. These retrieved parameters are used to numerically simulate the Ronchigrams with excellent agreement. This favorable comparison validates the accuracy of the wavefront recovery and provides a tool to examine the accuracy and robustness of this wavefront measurement technique.
我们通过详细的数值模拟验证了用于波前传感的 Ronchigrams 定量分析。对实验 Ronchigrams 的分析提供了波前像差、光束的 F/# 以及 Ronchi 光栅距近轴焦点的距离。这些反演参数用于对 Ronchigrams 进行数值模拟，结果吻合良好。这种良好的对比验证了波前恢复的准确性，并提供了一种工具来检验这种波前测量技术的准确性和稳健性。
