Abstract
In view of the fact that the details of the electro-hydraulic wave propagation is of great importance to the operational development of the extracorporeal shock wave lithotripter. In this paper, perfectly spherical shock waves were obtained with excellent repeatability by micro-explosions of underwater discharges, the movement of the spherical shock wave was measured by using a double exposure holographic interferometer and the interaction of the shock wave with the electrode was first observed. The experiments show that the method can be applied to studying the problem of the electro-hydraulic shock wave, especially to determining the wave front pressure distribution by measuring the wave front displacements.
