Abstract

Dispositif d’imagerie par ultrasons pour imager une zone (Z) d’une pièce (PI), le dispositif comprenant un traducteur ultrasonore (TUM) composé d’une pluralité de capteurs (EL) agencés sur une courbe fermée, chaque capteur étant apte à émettre et/ou recevoir une onde ultrasonore de surface dans/depuis la pièce (PI), chaque capteur (EL) étant agencé dans le traducteur ultrasonore (TUM) de manière à ce que, lorsque le dispositif est positionné pour imager la zone de la pièce, la direction normale au capteur (EL) intercepte la surface de la pièce avec un angle d’incidence prédéterminé permettant la propagation de l’onde ultrasonore à la surface de la pièce, le dispositif étant configuré pour réaliser une pluralité de séquences d’acquisitions successives de signaux ultrasonores, chaque séquence d’acquisition comprenant l’émission, depuis un capteur différent, d’un signal ultrasonore vers la zone (Z) puis la réception simultanée, par une pluralité de capteurs, d’une pluralité de signaux ultrasonores provenant de la zone (Z), le dispositif comprenant en outre une unité de traitement configurée pour calculer une pluralité de pixels I(P) correspondant chacun à un point (P) de la zone à partir des signaux ultrasonores acquis.
