    摘要: An ultrasonic inspection element and method are provided for improved ultrasonic inspection of curved entry surface parts (28). The transducer element (24) may be spherically focused, or have a flat surface. The transducer/mirror element combination (12, 24) is used to inspect through a concave or convex surface (26). A mirror element (12) shapes the sound beam relative to the shape of the curved surface (26) of the part (28) being inspected. Curvature of the mirror (12) is adjusted with a screw, rod, voltage modulator, or other suitable adjustment mechanism. An alternative mechanism includes multiple "quick disconnect" interchangeable curved mirror elements.

    摘要: A method of inspecting a component (10) includes immersing the component in a coupling medium (22) with material velocity C w and immersing an ultrasonic (UT) probe (20) having at least one transducer (12) in the coupling medium. The UT probe has a convex lens (14) with acoustic velocity C L and an acoustic impedance less than about 2.5 x 10 6 Rayls. The method further includes exciting the transducer to produce an UT pulse directed into the component and generating echo signals using the transducer as a receive element (12). An UT inspection system (30) includes UT probe, a pulser/receiver (32) configured to supply signal excitation pulses to the transducer element at a pulse repetition frequency (prf) of at least about 1000 Hz and a scanner (34) configured to scan the component with the UT probe at a scanning rate equal to the prf times a scanning increment.
