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

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.
