Abstract
Ultrasonic contact transducer with multiple ultrasonic emitting elements and means of bringing these elements into contact. This transducer is applicable particularly to non-destructive testing and comprises means (8, 10) for bringing elements (2) into contact with an object (6) to be checked and means (26, 28, and 34 to 40) of determining the positions of elements relative to the object, using means bringing elements into contact, to determine delay laws to be applied to excitation pulses of the elements, to generate a focussed ultrasonic beam (F).
Claims14
Ultrasonic contact transducer with multiple elements, this transducer being characterised in that it comprises means of bringing the elements into contact with the surface of an object to be checked and means of determining the positions of the elements relative to the object, using the means of bringing the elements into contact, and in that each element is at least an ultrasonic emitter and the emitting elements are rigid and are assembled to each other mechanically so as to form an articulated structure.
