Abstract
A scheme of registration of displacements of reflecting surfaces by the method of laser ranging with the use of a device developed for measuring the delay of optical signal propagation is considered. Results of test experiments aimed at studying the dusting parameters and spallation fracture of metals under shock wave loading with simultaneous applications of photonic Doppler velocimetry and laser ranging methods are reported.
