A Zernike-type one-dimensional phase-contrast x-ray microscope with a Wolter mirror was developed and tested. A Cu wire or an Al phase plate was placed at the back focal plane of the Wolter mirror objective. A dark-field image of a Cu mesh could be obtained at 9.00 keV by using the Cu wire as a direct beam stop, and a phase-contrast image could be obtained at 8.97 keV by using the same optics. A polyethylene telephthalate (PET) fiber of 9 μm in diameter could be obtained at 8.97 keV by using the Al phase plate, which could seldom be observed without the phase plate. These results agreed fairly well with simulated images.
