(a) Interferogram recorded at a distance corresponding to a maximum of Talbot visibility with the CCM. The interferometer gratings were set in such a way that their lines were oriented along the x direction. (b) Extraction of the relevant fringes from the interferogram shown in (a). (c) Local wavefront radius of curvature (abscissa) extracted from the interferogram in (b). The method used provides a value for the local wavefront radius of curvature at each y position averaged over the entire size of the image in (b) along the x direction.
