US 2007/0163348 A1 · Method and device for detecting discontinuities in a material region

Abstract

A method and a device for detecting discontinuities in a material region having at least one probe which has a plurality of ultrasonic transducer elements and having an evaluation and control device are proposed, in which the transducer elements are disposed diagonally at an angle to the surface of the material region and are actuated via delay elements in such a manner that a defocusing sound field is beamed in. The received signals of the transducer elements are supplied to a plurality of evaluation modules for parallel and simultaneous further processing for different angle values or angle ranges, the number of evaluation modules corresponding to the different angle values or ranges.

Dependent claims

A method for detecting discontinuities in a material region, comprising:

deploying a probe in a desired configuration relative to the material region;
activating a plurality of ultrasonic transducer elements of the probe to beam a defocused sound field into the material region, each ultrasonic transducer element being electronically controlled to achieve one of a desired angle and a desired range of angles of irradiation of the material region;
conducting in parallel a plurality of received signals reflected from the material region to a corresponding plurality of evaluation modules, each evaluation module evaluating a portion of the received signals corresponding to the one of a desired angle and a desired range of angles of irradiation of a corresponding one of the ultrasonic transducer elements;
and
analyzing data assembled by the plurality of evaluation modules to detect discontinuities in the material region.
