Concept of large FOV PSR-STHXM based on the inclined RML array. Under monochromatic plane-wave X-ray illumination, the array of RMLs generates X-ray line foci with a period equal to that of the multi-lens. The specimen is placed at the focal position and scanned through the X-ray line foci with step sizes slightly below the size of the line focus (FWHM). At each specimen step, an image [`low-resolution (LR) image' hereafter] is recorded. A high-resolution image is reconstructed from a set of LR images by the pixel super-resolution reconstruction algorithm. |
