High-Speed-X-Ray

High-speed X-ray technology enables synchronous, time resolved acquisition of an X-ray image in combination with an optical scan.
In this way, hidden structures and dynamic processes can be recorded at the same time.
Until now, high-speed imaging with time resolved acquisition of more than 1,000 images per second required highly specialized laboratory conditions and was therefore not suited to industrial use.

Dynamic processes, such as the observation of mixing and flow processes in fluids, can be vividly imaged using high-speed X-ray.

Fall test of a bicycle helmet with artificial skull. The impact can be tracked in slow motion using X-ray technology. There are around 11 milliseconds between the two images.

The new technology developed at Fraunhofer EZRT is particularly suitable for observing internal and external structures that undergo a one-time dynamic change.

For example, failure or deformation analysis can be reproduced in just as much detail as the flow and mixing process for fluids. The data obtained in this way enables a target/actual analysis of the temporal behavior with other data sources. Valuable insights can therefore be derived, especially for the predevelopment of new products or material mixtures.

High-speed X-ray technology is suitable for the following areas of application:

  • Failure and deformation analysis of materials
  • Deformation analysis of completely assembled vehicles
  • Flow and mixing processes for fluids
  • Predevelopment of products
