Low Energy X-ray Imaging

The development of innovative and novel X-ray Computed-Tomography (XCT) methods is an outstanding capability of Empa's Center for X-ray Analytics. Combined with state-of-the-art image reconstruction and processing, using in-house and commercial tools, it offers quantitative and qualitative non-destructive analysis for a wide range of materials and samples with spatial resolutions down to sub-micrometer levels.

Specific X-ray imaging methods are also available for specific materials. Low-attenuation contrast materials can be analysed using different X-ray Phase Contrast Imaging (PCI) methods including propagation-based, speckle-based methods and grating interferometry. Samples with nano-structures by X-ray Dark-Field Imaging (DFI) tools using speckle-based methods and grating interferometry. This extensive know-how is complemented with development projects for novel X-ray sources and detectors. The Center offers unique possibilities to advance X-ray analytics to new levels and make it accessible for material classes where it was not used before.

Basic and applied developments in the domains of bio- and life-sciences, personalized medicine, coating characterisation, wood analysis, micor/nano-structured scaffolds, additive manufacturing, rope improvements, bone-mineral density analysis, biofilm imaging, cartilage imaging, artefact reduction and many others are part of the activities of the group.
