Abstract

We demonstrate hard x-ray phase contrast imaging (XPCI) using a tabletop Talbot–Lau interferometer in which the x-ray source and source grating are replaced with an x-ray source with multiline metal targets embedded in a diamond substrate. This source realizes an array of linear x-ray sources of a few micrometers width without fabrication difficulty because of the shallow penetration depth of electrons irradiated to the metal targets. This enhances the coherence of x rays from each linear source and allows XPCI within 45 cm source–detector distance under 1.2 W input power for 8 keV x rays.
