Abstract

X-ray grating interferometers are configured to provide balanced paths (210/214, 212/216) so that interference fringes are produced with broadband x-ray beams (203). Beams propagating along one or more paths corresponding to one or more sets of diffraction orders can be used to generate respective fringes. Fringes are scanned by scanning one or more gratings (204, 206, 208), and the acquired fringe patterns are processed to produce specimen (250) images.
