With an a priori provided by a classical imaging method, could we design a network of emitters that can provide an optimal illumination of the target structure and a network of receivers that makes it possible to obtain an optimal 3D image? This question is motivated by the need to go beyond the current capabilities of non-destructive testing for buried infrastructures maintained by EDF. The objective is to develop a numerical method that is versatile enough to accommodate heterogeneous and complex environments, while remaining efficient and suited to high performance computing.
