Tunable X-ray dark-field imaging for sub-resolution feature size quantification in porous media

open access: yesScientific Reports, 2021
X-ray computed micro-tomography typically involves a trade-off between sample size and resolution, complicating the study at a micrometer scale of representative volumes of materials with broad feature size distributions (e.g. natural stones). X-ray dark-
