- Abstract
This contribution presents a method for the simultaneous determination of layer thicknesses and sound velocities of two layered structures. Thereby, the amplitude is evaluated to get additional information beside the time of flight. The amplitude of a reflected sonic wave depends of the position of the interface in the sound field of the probe and becomes maximal, if its within the focus. The focal point is varied by the use of an annular array and the amplitude as a function of the adjusted focus is evaluated. Thicknesses and sound velocities of different steel and aluminum plates after a water forerun are evaluated with this method.
