Abstract

In the X-ray and neutron Talbot (-Lau) interferometry, fabrication of phase or amplitude grating with a high-aspect ratio is a key factor to obtain high quality images. To improve the ability of the grating, evaluation of shape and thickness variation and feed-back to the fabrication process are essential. Here, it is shown that X-ray projection microscope with a spatial resolution of sub-micrometer is a powerful tool for the purpose. Three kinds of gratings have been evaluated by using a projection X-ray microscope with X-ray source size of 0.6 micrometer. Uniformity of thickness of the grating has been visualized nondestructively.
