Estimating the term…
A device and method of monitoring a surface defect on a proximal wall of a structure includes transmitting a generated ultrasonic bulk wave from an ultrasonic transducer array disposed on the proximal wall, the generated ultrasonic bulk wave being transmitted from the proximal wall as a spread wave having a central line angularly displaced relative to the proximal wall. The method includes determining at least one characteristic of the surface defect based on a reflected ultrasonic bulk wave sensed by the ultrasonic transducer array, the ultrasonic transducer array being disposed on the proximal wall and disposed to one side of the surface defect. The method may include determining at least one characteristic of the surface defect based on respective arrival times of the reflected ultrasonic bulk wave sensed by at least two ultrasonic transducers selected from the ultrasonic transducer array.
