Figure 3
(a) Plot of the intensity oscillation as a function of the grating position xg for a detector pixel over eight grating periods. The intensity values have been normalized and thus have arbitrary units. (b) Visibility map calculated [using (6)[link]] from the set of projections of the phase-stepping scan. Energy: 25 keV, third (fractional) Talbot distance.
