Description
We present a Full Waveform Inversion (FWI) approach designed to simultaneously identify interfaces and reconstruct sound speeds within layered media. This method hinges on synthetic data produced from our forward simulation. By reformulating the inverse problem into a Partial Differential Equation (PDE) constrained optimization, governed by the wave equation, we utilize a gradient descent algorithm to drive optimization. Our results vividly illustrate the efficiency and accuracy of the algorithm in achieving both interface identification and sound speed reconstruction.
In the subsequent section, we will present ongoing progress on performing our inverse algorithm, leveraging experimental measurements provided by our collaborators at the Medical University of Vienna. This may encompass validating the forward model, retrieving the source, and reconstructing the geometrical and physical parameters of such layered media using authentic data.
This is joint work with Peter Elbau, Michael Figl, Otmar Scherzer, and Lukas Zalka.
