Figure 2
Linear fit to the inverse grating magnification for the grating scan around the fractional Talbot order mT = 5/16 plotted against the displacement Δz as introduced in equation (2)[link]. The focus-to-detector and the focus-to-grating distance determined from the fit can be found in Table 1[link], together with the results for the other three realized Talbot orders. The theoretically expected position for a −π-shifting grating is indicated by the vertical dashed line. The orange dot marks the grating position used in the subsequent imaging experiments.
