Single Grating Interferometer for X-Ray Imaging

X-ray imaging is often based on the Talbot effect, and the periodic self-imaging of gratings. Following the work of N. Morimoto et al., we selected three types of phase gratings, with cross, checkerboard, and mesh patterns. The gratings are employed in a single grating interferometer, modeled as phase-only transmission functions (because the x-ray wavelength is much smaller than the smallest feature size of the grating), and their self-images are examined in VirtualLab Fusion.
