Abstract
L'invention concerne un appareil d'émission ou de réception d'ultrasons. Il comprend plusieurs éléments transducteurs d'ultrasons TR1 à TR32 disposés suivant une ligne; plusieurs circuits retardateurs à retards variables DC1 à DC32 qui appliquent des retards aux signaux émis et aux signaux reçus. Les circuits retardateurs sont constitués d'une mémoire dont les adresses correspondent aux différentes directions azimutales d'émission ou de réception et dont la sortie est connectée aux bornes de commande de commutateurs de transfert, eux-mêmes connectés à des lignes à retard à prises intermédiaires. L'invention s'applique notamment à des appareils de diagnostic par ultrasons, fonctionnant suivant un mode de balayage par secteurs circulaires.
