We focus on the reconstruction of defects, characterized by a Dirichlet condition, in a medium governed by the wave equation, from a single Cauchy boundary measurement. Our approach relies on the coupling of a non-standard level set method and a new version of the quasi-reversibility method adapted to the wave equation. We present several numerical results to illustrate the efficiency of the method. This is a joint work with Laurent Bourgeois and Dmitry Ponomarev.
