Abstract

Le module 50 comprend une enceinte 51 contenant un fluide dans lequel est immergé un dispositif de balayage réflecteur 70 et présentant une fenêtre 52 vers laquelle est tourné le dispositif de balayage, un transducteur 80 qui transforme de l'énergie électrique venant d'un moyen d'excitation en énergie ultrasonore et qui transforme l'énergie ultrasonore réfléchie en signaux électriques, le transducteur étant tourné vers le dispositif de balayage réflecteur de façon que le faisceau d'ultra-sons réfléchi sous-tende un angle alpha inférieur à 45 degrés environ.The module 50 comprises an enclosure 51 containing a fluid in which is immersed a reflective scanning device 70 and having a window 52 towards which the scanning device is turned, a transducer 80 which transforms electrical energy coming from a means of excitation into ultrasonic energy and which converts the reflected ultrasonic energy into electrical signals, the transducer being turned towards the reflector scanner such that the reflected ultrasound beam subtends an alpha angle of less than about 45 degrees.
