Ultrasonic seismic imaging of lava samples by viscoacoustic asymptotic waveform inversion: calibration and developments

Résumé

The object of this study is to estimate the viscoelastic parameters (compressionnal velocity and the intrinsic attenuation factor Q) of lava samples in acoustic tomography experiments by the use of an asymptotic viscoacoustic diffraction tomography method developped by Ribidetti et al 2000. 2.5 D common offset ultrasonic experiments are performed in a water tank laboratory.
