Laser-Excited Acoustics (LEA) vs. air-coupled UT (ACUT)
The comparison between XARION's LEA technology and the piezoelectric ACUT method clearly highlights the advantages of LEA. The images of the CFRP honeycomb structure provided by Northrop Grumman are clear.
- Through the 100-times broader bandwidth of the optical microphone, even the smallest defects in the honeycomb structure are visible.
- LEA demonstrates 10-times higher resolution compared to ACUT, while maintaining 5-times higher measurement speed.
- LEA sets a new benchmark for precision and efficiency in the non-destructive testing of lightweight components.
