X-ray phase contrast and X-ray fluorescence microscopes have been constructed with synchrotron radiation or laser plasma X-rays. Zone plates were mainly used for the X-ray phase contrast microscope and Wolter mirrors for the X-ray fluorescence microscope. Three dimensional X-ray phase contrast and X-ray fluorescence images were reconstructed from multi-directional projection or X-ray fluorescence images. Time-lapse observation of electrolysis of copper sulfate was made with a full-field X-ray fluorescence imaging microscope. Three dimensional element mapping became possible with X-ray fluorescence images. Several specimens such as plant seeds, red blood cells, diatoms and diamonds were three dimensionally observed.

用同步辐射或激光等离子体x射线构造了x射线相衬显微镜和x射线荧光显微镜。x射线相差显微镜主要采用带片，x射线荧光显微镜主要采用Wolter镜。由多向投影或x射线荧光图像重建三维x射线相衬和x射线荧光图像。采用全视野x射线荧光成像显微镜对硫酸铜电解过程进行了延时观察。借助x射线荧光图像，三维元素映射成为可能。对植物种子、红细胞、硅藻和钻石等标本进行了三维观察。
