Inverse obstacle problem for the non-stationary wave equation with an unknown background

Lauri Oksanen

We consider boundary measurements for the wave equation on a bounded domain $M \subset R^{2}$ or on a compact Riemannian surface, and introduce a method to locate a discontinuity in…

Solving an inverse problem for the wave equation by using a minimization algorithm and time-reversed measurements

Lauri Oksanen

We consider the inverse problem for the wave equation on a compact Riemannian manifold or on a bounded domain of $R^{n}$ , and generalize the concept of {\em domain of influence}. We…

An inverse problem for the wave equation with one measurement and the pseudorandom noise

Tapio Helin, Matti Lassas, Lauri Oksanen

We consider the wave equation $(\p_t^2-Δ_g)u(t,x)=f(t,x)$, in $R^{n}$ , $u ∣_{R_{-} \times R^{n}} = 0$ , where the metric $g = (g_{j k} (x))_{j, k = 1}^{n}$ is known outside an open and bounded set…
