New sources for Non Destructive Testing

More and more actors of the industrial and research world demand on complete and secure techniques to control the integrity of some critical components.

Our sources for X-radiography, based on laser-plasma interaction, offers unprecedented resolution, high-flux and complete security, as well as a great flexibility through a direct acces to numerical detectors for on-line diagnostics.

Access to numerical imaging Applications
Combination of ultra-small source point and high flux gives immediate access to numerical imaging:

  • Real time imaging
  • High resolution
  • Image processing (zoom, contrast…)
  • Automatical reject of the defective piece
  • Real time tomography
  • Micro-defaults detection
  • NDT of metallic alloys (>80 mm thickness)
