Schematic view of the XI system and demonstrative sample. The X-ray interferometer is composed of two-crystal blocks with two thin wafers acting as X-ray half mirrors, so the incident X-ray was divided, refract, and combined to generate two interference beams. Phase-shift caused by water in the tube placed in path I was detected by the intensity changes of the interference beams. The whole tube was rotated in a metallic cell filled with water cooled by a heatsink to perform computed tomography.
