Aiming for the fine observation of fast physical phenomena such as phonon propagation and laser ablation, phase‐contrast X‐ray imaging combined with a crystal X‐ray interferometer and the X‐ray free‐electron laser (XFEL) of the SPring‐8 Angstrom Compact Free‐Electron Laser has been developed. An interference pattern with 70% visibility was obtained by single‐shot exposure with a 15 keV monochromated...
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...
