A multi-channel PDV probe is designed to diagnose quantitatively the dynamic response of metal flyers in the collision region of two head-on sliding detonation waves by measuring the free surface velocity of particles normal to free surface near the collision plane. The results show typical regular reflection for W, Cu and Mach stem configuration for Sn, Pb, Ce in result of oblique colliding of two shock waves. These high spatial and time resolution velocity profiles can be used as early time stage benchmark for the validation of hydrodynamic codes and digital clue to retrace the kinetics leading to the formation of low density jet-like spiking in the collision region at late stage after colliding event.
