An Exact Redatuming Procedure for the Inverse Boundary Value Problem for the Wave Equation
Maarten V. de Hoop, Paul Kepley, Lauri Oksanen
Redatuming is a data processing technique to transform measurements recorded in one acquisition geometry to an analogous data set corresponding to another acquisition geometry, for…
Correlation based passive imaging with a white noise source
Tapio Helin, Matti Lassas, Lauri Oksanen +1
Passive imaging refers to problems where waves generated by unknown sources are recorded and used to image the medium through which they travel. The sources are typically modelled…
Recovery of time-dependent coefficient on Riemanian manifold for hyperbolic equations
Yavar Kian, Lauri Oksanen
Given , a compact connected Riemannian manifold of dimension , with boundary , we study the inverse boundary value problem of determining a time-depend…
Time reversal method with stabilizing boundary conditions for Photoacoustic tomography
Olga Chervova, Lauri Oksanen
We study an inverse initial source problem that models Photoacoustic tomography measurements with array detectors, and introduce a method that can be viewed as a modification of th…
Hyperbolic inverse problem with data on disjoint sets
Yavar Kian, Yaroslav Kurylev, Matti Lassas +1
We consider a restricted Dirichlet-to-Neumann map associated to a wave type operator on a Riemannian manifold with boundary. The restriction corresponds to the case where the Diric…
Global uniqueness in an inverse problem for time fractional diffusion equations
Yavar Kian, Lauri Oksanen, Eric Soccorsi +1
Given , a compact connected Riemannian manifold of dimension , with boundary , we consider an initial boundary value problem for a fractional diffusion…
