Mathematical resolution in imaging sources and small objects

In this presentation I will start by making a few remarks on source localization, when measuring the field on a sphere.  We will see that accuracy of the localization in mainly given by the wave number, but also that the situation is very different when  measuring data in the volume of the domain.  We will try to generalize this example by considering the scattering by a small object, and we will study numerical illustration  in the case of elasticity imaging.
