Zeelta develops spectral X-ray systems for non-destructive testing (NDT) and security screening. Prototypes have been built and tested for aviation security and industrial NDT. We run pilot projects with partners and adapt the systems to their tasks.
Key characteristics
Applications
Industrial NDT, aviation security, material research
Detector
HR-GaAs:Cr spectral photon-counting detector
Output
Structure image plus element distribution maps
Status
Validated prototypes; pilot projects with partners
IATA standard test set used to evaluate the spectral luggage scanning prototype.
Non-destructive testing
Spectral X-ray separates materials by their element composition. In tests the systems detected inclusions in aluminium alloys, surface cracks in turbine blades and defects in composite layers that conventional X-ray did not distinguish.
Security screening
A prototype for luggage scanning was tested with the IATA standard test set. Spectral data helps to tell organic materials, metals and hazardous substances apart.
Advantages
Element-sensitive inspection in one exposure
Higher spatial and time resolution
Designed with the analytical software as one system
