| Outline of Final Research Achievements |
The final goal of this project is to realize three-dimensional and high-sensitive projection X-ray microscope using a compact laboratory source near future. We have established several elemental techniques to realize this microscope. We have successfully described X-ray propagation in the X-ray microscope system by a wave-optics theory and developed a simulator that allows us to predict the X-ray propagation and design the X-ray microscope. We have constructed an X-ray projection microscope using a compact laboratory with a μm-size X-ray source and demonstrated that three independent images (absorption, fringe-phase, and visibility-contrast images) with Fresnel diffraction can be obtained by the X-ray microscope. We further developed elemental techniques including fabrications of structured X-ray target and flexible X-ray grating.
