Abstract:
3D image of a sample layout that enables a more e cient structure acquisition of heterogeneous sheet-like materials like paper with X-ray computed microscopy[1]. Sheets are very thin compared to their lateral extension, e.g., paper sheets consisting of cellulose-based bers. Local variations in the pore space might be considerably further apart than the sheet is thick. Hence, air or liquids transported through such sheets might experience locally dierent bottlenecks, for example, due to a reduced porosity or more torturous pathways. To quantify the number and properties of such bottlenecks it is necessary to probe many locations in the sheets while keeping a resolution large enough to resolve the pore space. Probing the sheet location by location using X-ray computed microscopy is highly time-consuming. The key idea of our sample layout is to permit the scan of multiple cutouts from the sheet at once. From the bottom to the top, the artistically enhanced image reveals the essential arrangement of the cutouts alike a peeled-o banana. Four paper strips, highlighted in color, are arranged into a stack.
