Abstract

Cette invention a trait à une technique d'imagerie par rayonnement à haute résolution, dans le cadre de laquelle, un espace objet est éclairé par une source, le signal diffusé étant détecté par plusieurs éléments récepteurs. Un processeur de signaux traite et combine les signaux diffusés provenant des différentes sources afin de produire une image focalisée.
