Abstract

The porosity of a workpiece, in particular a workpiece made of a fiber composite material is determined. An ultrasonic signal is injected into the workpiece and an ultrasonic echo signal is received from the workpiece. The variation of the amplitude of the ultrasonic echo signal with respect to the depth is used as a measure of the porosity of the workpiece material at the respective depth.
