Figure 2
Measured visibility of the moiré fringe pattern as a function of the distance d between the two gratings (top axis) and the beam separation b at the position of the first grating (bottom axis). The lines of the gratings were oriented along the horizontal direction. We show in blue the measurement with the CCM and in red that with the DCM. The envelope functions were fitted to Gaussian curves (dashed lines) and they are a measurement of the complex coherence function in the vertical direction.
