This paper presents a treatise on the determination of the complex amplitude of a monochromatic wave field from measurements obtained by a lateral shear interferometer. Both amplitude and phase distributions are recovered from the same set of measurements. Special consideration is given to the case of measurements with large shear. Here, the state of the art in the reconstruction of discontinuous wavefronts is extended by introducing a two-step process. In the first step, the phasors of the underlying wavefront are reconstructed across specific subsets of the measurement grid. In the second step, the individual reconstructions are combined by a novel (to the best of the author's knowledge) convolution approach in the Fourier domain, called residual phasor separation.
本文提出了一篇关于根据横向剪切干涉仪所获测量结果确定单色波场复振幅的论文。振幅和相位分布均从同一组测量结果中恢复。特别考虑了大剪切测量的情况。在此,通过引入两步法扩展了不连续波前重建的现有技术水平。第一步,在测量网格的特定子集中重建基础波前的相量。第二步,通过傅里叶域中一种新颖的(据作者所知)卷积方法(称为残余相量分离)将各个重建结果进行组合。
