Abstract:
1. A method of determining a dimension of a defect in a component, comprising: activating a linear array of ultrasonic transducers to propagate a focused ultrasonic beam along a first focal line perpendicular to the linear array; moving the focused ultrasonic beam across the defect in a first array direction while maintaining the first focal line perpendicular to the linear array; rotating the linear array; activating the linear array to propagate the focused ultrasonic beam along a second focal line perpendicular to the linear array and moving the focused ultrasonic beam across the defect along a second array direction that is non-parallel to the first array direction while maintaining the second focal line perpendicular to the linear array; and determining, by a processor, a distance between locations at which the reflection intensity of the focused ultrasonic beam reduces by a selected amount from a peak intensity of the focused ultrasonic beam in order to determine the dimension of the defect.
