Abstract
Phased array ultrasonic contact transducer, with a flexible wedge and a profilometer. This transducer applies to the non-destructive monitoring of an object and comprises: a set of elements that are rigidly integral with each other, at least part of the elements serving as ultrasound transmitters, a wedge whereof at least the front face is flexible to be applied against the surface of the object and the rear face of which is made integral with the set of elements, and a profilometer to measure surface variations and supply signals representative thereof to allow the transmitters to create a focused ultrasonic beam whereof the characteristics are controlled in relation to the object.
Claims11
A phased array ultrasonic contact transducer, said transducer comprising:
- a set of elements that are rigidly integral with each other, at least part of the elements serving as ultrasound transmitters, and
- a wedge having a front face, designed to be in contact with the surface of an object to be monitored, and a rear face that is opposite the front face and with which the set of elements is made integral,
- this transducer being characterized in that at least the front face of the wedge is flexible to be able to be applied against the surface of the object, and in that the transducer also comprises a profilometer to measure variations of the object's surface and supply signals representative of those variations, in order to allow the ultrasound transmitters to create a focused ultrasonic beam, the characteristics of which are controlled relative to the object.
