Abstract:

A plurality of flat or curved, wedge-shaped elements form the surface of a lens of an ultrasonic inspection transducer. The multiple wedge-shaped elements permit the ultrasonic energy from the transducer to be focused in a substantially straight line line focus parallel to the axis of the lens and deflected from a plane parallel to the wedge-shaped elements and at an oblique angle to the line focus. This achieves a concentration of ultrasonic energy along a line that can be projected into material as shear waves while maintaining equidistance from the transducers sensing wafer. This results in a concentration of ultrasonic energy that can detect small cracks in a workpiece. Author
