A Lipschitz stable reconstruction formula for the inverse problem for the wave equation

Abstract: We consider the problem to reconstruct a wave speed c ∈ C ∞ (M ) in a domain M ⊂ R n from acoustic boundary measurements modelled by the hyperbolic Dirichlet-to-Neumann map Λ. We introduce a reconstruction formula for c that is based on the Boundary Control method and incorporates features also from the complex geometric optics solutions approach. Moreover, we show that the reconstruction formula is locally Lipschitz stable for a low frequency component of c −2 under the assumption that the Riemannian manifold… Show more

“…We refer to this paper for a longer bibliography in the case of the wave equation. In [30] Liu and Oksanen consider the problem to reconstruct a wave speed c from acoustic boundary measurements modelled by the hyperbolic Dirichlet to Neumann map. They introduced a reconstruction formula for c that is based on the Boundary Control method and incorporates features also from the complex geometric optics solutions approach.…”

“…However in practice some non trapping assumptions on the domain Ω are required for the hypothesis of the Corollary 1 to hold c.f. [20,35,33]. These non trapping assumptions may not be required if using the boundary control method and the full source to solution map [4,3].…”
