(a) Normalized grating diffraction pattern at the detector plane. Intensity, coherence and wavefront profiles of (b) the transmitted beam without grating and (c) the zeroth-order and (d) the first-order beam diffracted by the grating. Line scans of the wavefront profiles [red solid line in (b3, c3, d3)] were plotted [blue solid lines in (b4, c4, d4)] and verified by the results of the AC method [red dashed lines in (b4, c4, d4)]. |
