X-ray phase contrast imaging by compact Talbot-Lau interferometer with a single transmission grating.

Abstract

We performed x-ray phase contrast imaging (XPCI) by Talbot-Lau interferometer using only a single transmission grating. Multiline metal targets embedded in a diamond substrate were irradiated with electrons to generate an array of x-ray lines of 1 μm width, which allowed XPCI within a 1 m source-detector distance in a configuration without a source or absorption grating. We directly resolved the self-image of the phase grating of 3 μm pitch using an x-ray image detector of 24 μm pixel size and successfully obtained absorption, differential phase, and dark-field images for 8 keV x rays.
