Abstract

We present a non-iterative method as well as its linearization to reconstruct an isotropic acoustic speed from the near-field data represented by the Neumann-to-Dirichlet map. The algorithm is designed based on the boundary control method and involves only stable computation. Numerical validation is provided with both full and partial data.
