摘要： The invention relates to a method for providing a structural condition of a structure, comprising providing an excitation wave generator; providing an excitation wave sensor; injecting an excitation burst wave into the structure using the excitation wave generator; obtaining a measured propagated excitation burst wave using the excitation wave sensor; correlating the measured propagated excitation burst wave with one of a plurality of theoretical dispersed versions of the excitation burst wave; and providing an indication of the structural condition of the structure corresponding to the correlated measured propagated excitation burst wave. The method may offer a better localization of the reflection points and thus of the potential defects present in a structure under inspection, when compared with a group velocity-based or time-of-flight (ToF) approach. The method may be particularly useful for structural health monitoring (SHM) and Non-Destructive Testing (NDT). The method may also enable determination of the mechanical properties of the structure.
