Institute for Photon Science and Synchrotron Radiation

Imaging group

The Imaging group at IPS idevelops instrumentation and components, methods and techniques for X-ray imaging.

The main expertise of the group concerns full-field methods for:

  • projection imaging
  • microscopy
  • 3D tomographic imaging based on absorption, phase, and Bragg/Laue diffraction contrast.

Synchrotron imaging methods with spatial resolution in the micrometer and nanometer range are increasingly relevant for material research and diagnostics in engineering sciences, micro system- and nanotechnologies, for structural imaging in nanobiology and life sciences, for non-destructive testing of components and devices, for paleontology, cultural heritage, and other fields.

These methods close the gap between conventional 2D and 3D imaging performed with techniques based on X-ray table-top sources and electron microscopy methods, for example the gap in spatial resolution between about 10 μm and several tens of nanometers. X-ray imaging techniques are largely non-destructive and allow using and combining various contrast mechanisms (absorption, X-ray fluorescence, Fresnel and Bragg diffraction, dichroism, etc.) to image geometrical, chemical, and crystallographic structures of samples.
