Title (EN) ULTRASONIC WAVE ENERGY ELECTRONIC B-SCAN IMAGING APPARATUS
(FR) APPAREIL DE MISE EN IMAGE A BALAYAGE-B ELECTRONIQUE PAR ONDES ULTRA-SONORES
Abstract: front page image
(EN)A transducer (102) comprising a longitudinal bar of piezoelectric material (200) having one longitudinal face substantially covered with a first electrode (202) and the opposite longitudinal face in contact with a predetermined plural number of separate electrodes (204-1, 204-2, ... 204-n) spaced along the length thereof, permits all detected echoes to be processed by a single low input impedance amplifier (206) permanently coupled to the first electrode.
(FR)Un transducteur (102) comprenant une barre longitudinale en materiau piezoelectrique (200) ayant une face longitudinale substantiellement recouverte par une premiere electrode (202) et la face longitudinale opposee en contact avec une pluralite predeterminee d"electrodes separees (204-1, 204-2 ... 204-n) espacees sur sa longueur, permet a tous les echos detectes d"etre traites par un seul amplificateur a faible impedance d"entree (206) couple en permanence a la premiere electrode.
