The dark-field signal changes as a function of the correlation length (\(\upxi )\). The sample consists of mixed particles with either a mean nomimal pore size of 50 or 150 nm. Tomograms were obtained at eighteen correlation lengths between 24.83 and 434.60 nm. Dark-field cross-sections of the five smallest correlation lengths are show.
