    摘要： A method of inspecting a component includes immersing the component in a coupling medium with material velocity cw and immersing an ultrasonic (UT) probe having at least one transducer in the coupling medium. The UT probe has a convex lens with acoustic velocity cL and an acoustic impedance less than about 2.5×106 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. An US inspection system includes UT probe, a pulser/receiver 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 configured to scan the component with the UT probe at a scanning rate equal to the prf times a scanning increment.

    摘要： An ultrasound inspection system is provided. The ultrasound inspection system includes a pulse echo transducer and a processor that is operationally coupled to the transducer. The system facilitates reducing noise in an echo received from a near surface inspection area of a component. To facilitate reducing noise the processor is programmed to extract an A-scan data set from a B-scan image of the component. The processor is also programmed to locate a half-max point of a front surface echo in the A-scan data set. The processor is also programmed to locate the front surface of the component using a first zero crossing in a derivative of the A-scan data set.

    摘要： An ultrasonic transducer system has at least one ultrasonic transducer. Each ultrasonic transducer includes a housing having a wall that is made at least in part of an organic structural material that is substantially impervious to water; and an ultrasonic sensor element located at least in part within the housing and positioned to transceive ultrasonic signals. The wall is preferably cylindrical in shape and made of polyvinylchloride plastic. An electrically grounded shield is within the housing and adjacent to an interior wall surface. The ultrasonic sensor element may be a piezoelectric copolymer film ultrasonic sensor element.
