Passive Imaging with Ambient Noise Under Wave Speed Mismatch: Mathematical Analysis and Wave Speed Estimation
Zetao Fei, Josselin Garnier
It is known that waves generated by ambient noise sources and recorded by passive receivers can be used to image the reflectivities of an unknown medium. However, reconstructing th…

Probing the speckle to estimate the effective speed of sound, a first step towards quantitative ultrasound imaging
Josselin Garnier, Laure Giovangigli, Quentin Goepfert +1
In this paper, we present a mathematical model and analysis for a new experimental method [Bureau and al., arXiv:2409.13901, 2024] for effective sound velocity estimation in medica…
