Abstract
A sensor for determining the position of shock wave pulses of a shock wave source comprises a device for holding a metal foil in the region of focus for the shock wave source. The metal foil is held to extend perpendicular to the main propagation direction of the pulses and the incidence of the pulses on the metal foil will cause a bulge-like deformation of the material to be formed at the point of incidence. The deformation in the foil can be optically measured, for example, by evaluation in terms of location, diameter, depth, profile and volume to obtain conclusions about the position of the center of the focussed shock waves and also the power or intensity of the shock waves.
