Device and method for the control of ultrasonic transducers to measure metal profiles
First Claim
1. A device for testing metallurgical products, comprising:
- an ultrasonic sensor comprising a plurality of elementary transducers which are operable independently of each other and which are distributed in accordance with a two-dimensional pattern;
a first electronic component configured to excite each of the elementary transducers in accordance with at least one temporal law corresponding to a burst of ultrasonic waves in a line of sight from the plurality of elementary transducers; and
a second electronic component configured to process at least a portion of signals captured by each of the elementary transducers,wherein each temporal law is arranged such that a corresponding burst of the ultrasonic waves from the plurality of elementary transducers jointly produces a beam of ultrasonic waves which is divergent about the line of sight with increasing distance from the ultrasonic sensor, the first electronic component is configured to control the divergence about the line of sight by the at least one temporal law, and the at least one temporal law produces a defocused primary beam jointly from the plurality of elementary transducers.

Abstract
A device, and corresponding test method, for testing metallurgical products including an ultrasonic sensor including a plurality of elementary transducers which can be operated independently of each other and are distributed in accordance with a two-dimensional pattern is described. A first electronic component is configured to excite each of the elementary transducers in accordance with at least one temporal law corresponding to a burst of ultrasonic waves in a line of sight. A second electronic component is configured to process at least a portion of the signals captured by each of the elementary transducers. Each temporal law is arranged such that the corresponding burst produces a beam of ultrasonic waves which is generally divergent about the line of sight on moving away from the ultrasonic sensor.

23. A method for testing metallurgical products, comprising:
-
providing an ultrasonic sensor including a plurality of elementary transducers which are operable independently of each other and which are distributed in accordance with a two-dimensional pattern; exciting, with a first electronic component, each of the elementary transducers to produce a burst of ultrasonic waves that jointly correspond to a beam which is divergent about a line of sight from the plurality of elementary transducers on moving away from the ultrasonic sensor; controlling, with the first electronic component, the divergence of the beam about the line of sight by at least one temporal law corresponding to the burst of ultrasonic waves in the line of sight, and the at least one temporal law produces a defocused primary beam jointly from the plurality of elementary transducers; and processing at least a portion of signals captured by each of the elementary transducers in response to the ultrasonic burst. - View Dependent Claims (24)
