在SPring-8的光束线39XU处构造了具有Wolter型掠入射镜物镜的X射线荧光成像显微镜。用能量范围为6 - 10keV的单色X射线激发试样的X射线荧光，记录试样（Cu. Ni和Fe线）从50个不同的视角，获得三维断层重建。这些线可以通过改变激发X射线的能量来选择性地重建。人造金刚石也可以三维成像。(C)2001 Elsevier Science B.V.保留所有权利。
An X-ray fluorescence imaging microscope with a Wolter-type grazing-incidence mirror objective was constructed at beamline 39XU of SPring-8. Monochromatic X-rays in the energy range 6-10keV were used for X-ray fluorescence excitation of the specimens, Recording X-ray fluorescence images of a test specimen (Cu. Ni and Fe wires) from 50 different angles of view, three-dimensional tomographic reconstructions were obtained. These wires could be reconstructed selectively by changing the energy of the excitation X-rays. A synthetic diamond could also be imaged three-dimensionally. (C) 2001 Elsevier Science B.V.
