Title (EN) APPARATUS FOR ULTRASONIC IMAGING OF FAULTS
(FR) APPAREIL DE MISE EN IMAGE ULTRASONIQUE DE DEFAUTS
Abstract: front page image
(EN)An apparatus for the ultrasonic imaging of faults focuses an acoustic image, located internally of an object (3), onto an ultrasonic receiving means (23) to produce the image of a desired fault present within the object (3). The apparatus includes means (110) for transmitting ultrasonic waves in such a manner as to scan the desired fault within the object, thereby assuring that ultrasonic waves will not be transmitted toward such portions of the object as need not be scanned. The apparatus further includes gate means (150) which causes the ultrasonic receiving means (23) to receive the acoustic image corresponding to a scan in accordance with the scanning operation performed by the ultrasonic wave transmitting means (110). This eliminates reception of acoustic images other than those of the desired faults to improve the quality of the fault image.
(FR)Un appareil de mise en image ultrasonique de defauts focalise une image acoustique, situee a l"interieur d"un objet (3), sur des moyens de reception ultrasonique (23) pour produire l"image d"un defaut present dans l"objet (3). L"appareil comprend des moyens (110) de transmission d"ondes ultrasoniques de maniere a explorer le defaut en question de l"objet s"assurant ainsi que les ondes ultrasoniques ne sont pas transmises vers les parties de l"objet qui n"ont pas besoin d"etres explorees. L"appareil comprend en outre des moyens de porte (150) qui permettent au moyen de reception ultrasonique (23) de recevoir une image acoustique correspondant a une exploration effectuee par les moyens de transmission d"ondes ultrasoniques (110). Ceci permet d"eliminer la reception d"images acoustiques autres que celles des defauts, ameliorant ainsi la qualite de l"image des defauts.
