<p>The invention relates to an ultrasonic contact transducer comprising multiple elements, a flexible shoe and a profilometer. This transducer is applicable in particular for the non-destructive testing of an object and comprises: an array of elements (10) rigidly fastened together, at least some of which serve as ultrasound emitters; a shoe (6), at least the front face of which is flexible so as to be able to be applied against the surface of the object (2) and the rear face of which is fastened to the array of elements; and a profilometer (8) for measuring surface variations and for delivering signals representative of said surface variations, in order to allow the emitters to generate a focussed ultrasonic beam (F), the characteristics of which are controlled relative to the object.</p> |
