Feasibility study of the sub-pixel scanning method for single-exposure x-ray refraction imaging by Talbot-Lau interferometer using an a-Se direct conversion type FPD

摘要

We propose a Sub-Pixel Scanning (SPS) method for imaging the refraction of X-rays by an object with a single exposure.The key feature of our SPS method is that the area where the G2 grating masks the self-image of the G1 gratingcyclically changes along th
