In situ calibration of acoustic emission transducers by time reversal method
Original language description
Conventional methods of calibration of acoustic emission transducers require an already calibratedreference transducer and/or special test specimen. Moreover the calibration results are not directlytransferrable to practice, since they are dependent on bonding conditions and mechanical propertiesof the medium. In this paper a reference-free in situ calibration method is proposed. It is based on acombination of time reversed acoustics and reciprocal calibration and allows accurate determination oftransducers’ frequency responses. The method was developed and successfully experimentally verifiedassuming that frequency response of used transducers is the same for transmission and reception. Sub-sequently the analysis was extended considering irreversible transducers and applied to experimentaldata. Of five tested transducers, three were found reversible and two demonstrated resonance frequencyshift in lower frequency region between reception and transmission.
