Imaging of micro structures and spatial inhomogeneities within object.

2D & 3D information about

- microstructural geometry and its statistical properties
- chemical composition
- strainfields / defect distribution in crystalline structures

Absorption Contrast Imaging Phase Contrast Imaging
  • down to sub-µm spatial resolution
  • down to ms temporal resolution
  • monochromatic radiation (quantitative imaging)
  • k-edge substraction imaging
  • edge-detection imaging
  • holographic imaging
Fluorescence imaging Experimental techniques
  • Elemental composition in three dimensions
    with µm spatial resolution
  • Trace element concentrations below pg/µg
  • Confocal x-ray fluorescence microprobe
