Standoff inspection using geometry-informed full-wavefield response measurements

A system for inspecting a structure, the system comprising:

• a vibrometer configured to measure acoustic responses in portions of the structure along a scan path to acoustic excitation of the structure;
• a ranging device configured to measure distances to the portions of the structure along the scan path;
• and
• one or more physical processors configured by machine-readable instructions to:
• generate a three-dimensional point cloud based on the acoustic responses in the portions of the structure and the distances to the portions of the structure, the three-dimensional point cloud including points representing geometry of the portions of the structure, the points associated with the acoustic responses in corresponding portions of the structure;
• and
• identify one or more defects in the structure based on an analysis of the three-dimensional point cloud, wherein the identification of the one or more defects in the structure based on the analysis of the three-dimensional point cloud includes:
• determination of wavefield spatial patterns in the portions of the structure based on the acoustic responses within the portions as indicated by the three-dimensional point cloud;
• and
• identification of the one or more defects in the structure based on the wavefield spatial patterns in the portions of the structure.
