Abstract (en)
[origin: WO02079724A1] The invention relates to ultra sonic measurement of the thickness of a partial layer in a multi-layered structure with reduced boundary surface reflections. A plurality of transmission pulses are produced on a predetermined point on the structure with the help of an ultra sonic probe head. The resulting echo signal associated with a transmission pulse are recorded digitally as an HF image. A plurality of wall thickness echo periods from different running periods are superimposed in a homologous manner with the aid of a computer program.
