N2 - A nonplanar three-beam case X-ray interferometer was tested for high spatial resolution phase-contrast X-ray imaging. The interfering beam is formed by simultaneous Bragg-case X-ray diffraction in this interferometer, and this avoids the type of image blurring due to the spreading of the X-ray wave field that occurs in the crystal of a triple Laue-case (LLL) X-ray interferometer. The test was performed using 10.3 keV synchrotron radiation X-rays, and fine interference fringes, which smear when a conventional LLL interferometer is used, were observed for a plastic phantom sphere.
