This talk is devoted to determine optimal sensors location to achieve photoacoustic reconstruction. We check an appropriate location of sensors for two series of measures, in two steps: first, we reconstruct possible initial data by solving a worst-case design like problem. Second, we determine from the knowledge of these initial conditions the optimal location of sensors for observing in the best way the corresponding solution of the wave equation.
