Scanning and projection nanotomography acquisition schemes.
(a) Distribution of Pt of a coated AFM tip measured with the x-ray scanning nanoprobe. (b) SEM micrograph provided by Nanosensor Co. (with their agreement).
(a) Fluorescence tomography reconstructed slice with chemical identification. Platinum is in orange (external layer) and silicon in blue. (b) Holotomography color-coded image of the same slice; the image has been segmented into two regions having different densities. (c) 3D chemical image. (d) 3D density image.
Total fluorescence spectrum and 2D elemental images of one reconstructed slice. Experimental data (black, noisy), fitted background (green), and fitted fluorescence peaks (red, noiseless). Nonindexed peaks are lines, , and lines.
