Air-Coupled Ultrasound Inspection of Various Materials

Ultrasonics, 2002
Conventional ultrasound inspection, a standard non-destructive testing method, uses a coupling medium (e.g. water) because of impedance mismatch. This liquid contact is a drawback because it prevents inspection of many materials. There is a need, then, for air-coupled ultrasound testing, which is now feasible because of low impedance focused narrow ...

New Opportunities for NDE With Air-Coupled Ultrasound

NDT and E International, 2006
Abstract The area of NDE-applications of air-coupled ultrasound is expanded substantially for a weakly focused acoustic wave incident obliquely on a plate-like sample at an angle of ‘resonance’ transmission. Such a focused slanted transmission mode (FSTM) combines the benefits of plate wave excitation with a high spatial resolution and enables to ...

Nonlinear Modulation Technique for NDE With Air-Coupled Ultrasound

Ultrasonics, 2004
The present study is aimed at expanding flexibility and application area of nonlinear acoustic modulation (NAM-) technique by combining the benefits of noncontact ultrasound excitation (remote locating and imaging of defects) with sensitivity of nonlinear methods in a new air-coupled NAM-version.

Through-Thickness Characterization of Solids by Wideband Air-Coupled Ultrasound

Ultrasonics, 1995
Abstract A non-contact inspection system employing wideband air-coupled ultrasound has been used for the characterization of thin solid material. Generation and detection of pulsed ultrasound were accomplished on opposite sides of the sample (in the through-thickness mode) using micromachined air-coupled capacitance transducers.

Sensitivity of Air-Coupled Ultrasound and Eddy Current Sensors to Bearing Fault Detection

Tribology Transactions, 2008
For decades, vibration and oil analysis have usually been used to detect early bearing faults and track their progression over time. Progress has been seen in condition monitoring through vibration analysis of rolling element bearings using improved sensors and advanced signal processing techniques. In this paper, the authors investigate the use of air-
