Signal enhancement in X-ray Talbot interferometry with a pair of concave and convex parabolic phase gratings

X-ray Talbot and Talbot–Lau interferometers consisting of transmission gratings are widely used for X-ray phase imaging, which depicts soft materials. This study exploits the use of a pair of concave and convex parabolic gratings instead of a conventional rectangular phase grating to enhance the pha...
