Feasibility study of phase-contrast X-ray laminography using X-ray interferometry

For fine observation of laminar samples, phase-contrast X-ray laminography using X-ray interferometry was developed. An imaging system fitted with a two-crystal X-ray interferometer was used to perform the observations, and the sectional images were calculated by a three-dimensional iterative reconstruction method. Obtained images of an old flat slab of limestone from the Carnic Alps depicted fusulinids in the Carboniferous period with 3   mg   cm − 3 density resolution, and those of carbon paper used for a fuel-cell battery displayed the inner fibrous structures clearly.
