Laser-Excited Acoustics (LEA) vs. water-coupled UT

Same Detection Quality. No Coupling Medium Required.

LEA proves its competitive advantage against contact-based methods (1 MHz waterjet UT) on a CFRP honeycomb structure, provided by Airbus. 

  • Different types of defects were reliably detected, completely without any coupling media. 
  • The defect contrast fully matches that of established water-coupled testing methods. 
  • LEA demonstrates the ability to extend UT to sensitive materials and process environments without compromising on speed or resolution.
