Abstract
The invention relates to a test probefor the non-destructive testing of a workpiece by means of ultrasonic sound. The test probe has an ultrasonic transducerfor the generation of an ultrasonic field, which is coupled acoustically to a delay line body, which is provided to be attached for a coupling of the ultrasonic field into the workpiece on a surface of the workpiece. Furthermore, the invention relates to a family of test probes as well as to a testing device for the non-destructive testing of a workpiece by means of ultrasonic sound, with a test probe, whose ultrasonic transducerhas a majority of independently controllable individual oscillators. Furthermore, a control unitis provided, which is equipped to control the individual oscillators of the ultrasonic transducerwith phase accuracy in such a way, that a sound field rotationally symmetrical to the central beam is generated. The test probe or the family of test probes and the testing device are suitable in particular for the angular intromission of sound or for a utilization on curved workpiece surface areas.
