Figure 3
Simulated fringe visibility without the incorporation of a CCF. The results were obtained by propagating a plane wave incident on the checkerboard grating at 8.500 keV. The ordinate is the amplitude of the second-order term in the Fourier transform of the intensity normalized to the zeroth order. Absorption in the gold squares of the grating was incorporated. An effective z scale to account for stretching due to a spherical incident wave was also incorporated. The line connects calculated results at points at 4 mm separation, in order to correspond to z locations at which beamline data were obtained.
