Local Ultrasonic Resonance Spectroscopy: A Demonstration on Plate Inspection

Authors:

Janez Rus, Christian Grosse

Contents:

• Local ultrasonic resonance spectroscopy (LURS) is a new approach to ultrasound signal analysis
• XARION’s ultrasonic sensor was used for a LURS scan of a carbon fiber reinforced polymer plate. An advantage in characterizing the features of the specimens could be demonstrated
