Abstract
The method for calibrating an inspection instrument coupled with acoustic transducers disposed at circumferential positions distributed around a surface of an elongated object to inspect generally has the steps of: for each one of the circumferential positions, measuring a first and a second received signal using two acoustic transducers disposed at two axial positions along the object, the received signals resulting from the propagation of an acoustic guided wave signal along the object; identifying an acoustic mode according to the first received and the second received signals using a known period of time associated with the propagation of the acoustic guided wave signal between the two axial positions along the object; and determining a coupling coefficient associated with the acoustic mode, the coupling coefficient being indicative of the coupling of the acoustic transducers on the object; and calibrating the inspection instrument coupled to the object based on the coupling coefficients.
