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.
