Claim 0:
1. A method for performing ultrasound testing of a component comprising a first material layer and a second material layer bonded by an adhesive layer, the method comprising:
applying input ultrasound waves to the component to cause longitudinal propagation of ultrasonic guided waves through the first material layer, the second material layer and the adhesive layer;
acquiring acoustic waves from the component, wherein the acoustic waves are produced by the longitudinal propagation of the ultrasonic guided waves;
generating a signal representation of the acoustic waves;
comparing the signal representation of the acoustic waves to a plurality of reference signals to identify a characteristic of the adhesive layer; and
outputting an output signal indicative of the characteristic of the adhesive layer.
