Abstract
A tube inspection system that includes a guided-wave-transducer mechanism (GWTM) that is associated with a tube that is being inspected. The GWTM can have one ring with ‘N’ guided-wave transducers (GWTs) distributed thereon, and another ring with ‘M’ guided-wave transducers (GWTs) distributed thereon. A controller excites mechanical waves by the GWTs of the first ring that propagate in the wall of the tube being inspected and along its axis. The ‘M’ GWTs of the second ring obtain received mechanical waves and convert them to electronic signals. The ‘M’ electronic signals are processed to provide a measured signal in which a wanted mode is enhanced.
