Outline of Final Research Achievements

We propose super-resolution technique in transmission X-ray imaging, in which an array of small X-ray sources is utilized. In this technique, high-spatial-resolution X-ray image equivalent to that obtained with a single small X-ray source is reconstructed from the observation using the source array. We demonstrate the principle of this technique using multi-dot gold targets embedded in a silicon substrate in an X-ray imaging system. In X-ray imaging with an array of six X-ray sources of 1 um diameter, a line & space pattern of 0.6 um width is clearly resolved, indicating the effectiveness of this technique.
