Abstract

L'invention concerne un tomographe actif servant à détecter des informations sur des structures inconnues en mode 3D. Le tomographe actif envoie depuis un émetteur des signaux d'émission avec une quelconque fonction de modulation et enregistre dans toute leur intégralité d'informations, les signaux qui sont réfléchis au niveau d'une structure inconnue ou qui la traversent et sont affaiblis du fait de l'absorption. Ce tomographe peut s'utiliser partout où une structure inconnue est noyée dans un milieu, comme par ex. c'est le cas en médecine lors de l'examen du corps humain ou animal. Le tomographe actif se caractérise en ce que les modules acoustiques munis d'éléments émetteurs et récepteurs sont disposés dans des positions connues, les uns par rapport aux autres, de manière que leurs espaces de sonorisation et leurs espaces de réception se chevauchent sur la structure à examiner.
