Abstract

A method and apparatus for detecting an inconsistency in an object. A signal sent from a first transducer unit is received at a second transducer unit. The signal is sent along a path through an object from the first transducer unit to the second transducer unit. The second transducer unit has segments. A velocity is identified at each segment in the segments for a number of modes for the signal to form identified velocities. A determination is made as to whether the inconsistency is present along the path through the object using the identified velocities for the number of modes for the signal.
