Figure 2
Representative examples of data analysis in grating interferometry, illustrating the key steps described in Sections 2.2.1[link] and 2.2.2[link]. These examples are shown for demonstration purposes and are not necessarily linked to the beamline measurements presented later. (a) Fourier spectrum of an interferogram, highlighting harmonic peaks. (b) Interferogram period pz as a function of z, with a linear fit. (c) Visibility curve V(z) with the red curve showing the full fit and the blue curve representing the coherence decay envelope.
