Inspection of a structure with a sloped back wall

Abstract:

A signal is sent into a first surface of a structure at an angle relative to the first surface of the structure using a transducer array, wherein the structure has a second surface with a portion non-parallel to the first surface. An ultrasound response signal is formed at the portion of the second surface of the structure. The ultrasound response signal is received at the transducer array.
