The principle of profile reconstruction in intra-focal setup (after Spiga et al., 2013aBB20). A grazing-incidence mirror is illuminated with X-rays and the reflected beam is collected by an imaging detector in intra-focus position. (a) If the mirror had a perfect shape, the intra-focal image would be uniform. (b) In the presence of mirror deformations, the intensity distribution is modulated as a function of the local curvature in the longitudinal direction.
