Abstract
An x-ray interferometric imaging system in which the x-ray source comprises a target having a plurality of structured coherent sub-sources of x-rays embedded in a thermally conducting substrate. The system additionally comprises a beam-splitting grating G1 that establishes a Talbot interference pattern, which may be a π phase-shifting grating, and an x-ray detector to convert two-dimensional x-ray intensities into electronic signals. The system may also comprise a second analyzer grating G2 that may be placed in front of the detector to form additional interference fringes, a means to translate the second grating G2 relative to the detector. The system may additionally comprise an antiscattering grid to reduce signals from scattered x-rays. Various configurations of dark-field and bright-field detectors are also disclosed.
