Abstract:

A neural network based spectrum classifier for classifyng spectra acquired in ultrasonic resonance spectroscopy is presented. The performance of the classifier is demonstrated using results of its application to detection of disbounds in adhesivly joint multilayer aerospace structures using Fokker Bond Tester resonance instrument
