Abstract

X-ray phase imaging with a single phase grating based on the fractional Talbot effect is described. A phase grating with an 8 μm pitch was placed behind a weakly absorbing object and illuminated with partially coherent 17.7 keV X-rays. Intensity patterns downstream of the grating were recorded with a high-resolution image detector. By the fringe scanning method, an X-ray wavefront inclination by the object was obtained. Phase tomography was performed and Moosethe three-dimensional structure of a piece of a polymer blend was revealed with an 8 μm spatial resolution and a 9mg/cm3 detection limit of density deviation.
