Characterization of Ultrasonic Immersion Transducers
NDT & E International, 1990 In any ultrasonic NDE experiment, the distributed field properties of the transducer involved represent an important aspect of the overall measurement process. The normal velocity profile across the active face of the transducer is typically used to characterize these properties.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Ultrasonic metal sheet thickness measurement without prior wave speed calibration [PDF]
, 2013 Conventional ultrasonic mensuration of sample thickness from one side only requires the bulk wave reverberation time and a calibration speed. This speed changes with temperature, stress, and microstructure, limiting thickness measurement accuracy ...

Acoustographic evaluation of ultrasonic transducers
NDT & E International, 1989 In order to have confidence in the nondestructive evaluation data generated by an ultrasonic system, it is important to establish the adequacy and reliability of the ultrasonic transducer employed in the system. This is usually accomplished by characterizing the electro-mechanical properties and the radiated acoustic field distribution of the ...
