Abstract
A test head for testing a workpiece has an ultrasonic transducer configuration with a plurality of ultrasonic transducers. The test head further contains a carrier matched to a surface contour of the workpiece, a damping layer arranged on the carrier, and a flexible conductor foil configuration, which is arranged on the damping layer and has a number of electrically separated conductor tracks which corresponds to the number of transducer elements. The transducer elements are arranged on the conductor tracks alongside one another in at least one row, and in each case are electrically contact-connected to one of the conductor tracks.
