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.

X-ray absorption (left), phase contrast (right) images, and the section profiles of PMMA and PTFE spheres. These images were obtained using multiline Mo (upper) and Cu (lower) targets, respectively. Section profiles of the phase gradient dΦ/dx(π/mm) show those along the lines of the PMMA (blue) and PTFE (red) spheres in the XPCIs. The exposure time of the individual raw images during the phase-stepping process is 60 s.
