A determination of cracks using topology optimization In 3-D scalar wave scattering field is considered. We introduce the cost function which is the misfit function between the observed data and the numerical data on the boundary of the domain having the cracks. We determine the cracks as the minimizer of the cost function using the topological derivative. The determination of two cracks having the less forecast information are shown in this paper.
