Abstract :
A two-stage method for solving an applied potential tomography problem is developed. In the first stage, using optimal control techniques, an approximation of the potential in a domain Ω is computed on the basis of what is known on the boundary of Ω. In the second stage, using the singular perturbation method, an image of the conductivity distribution in Ω is reconstructed
