Title: Optically recording velocity interferometer system (ORVIS) for subnanosecond particle-velocity measurements in shock waves

Abstract

An optically recording velocity interferometer system (ORVIS) has been developed to measure particle velocity with subnanosecond resolution for shock waves in condensed matter. The fringe pattern of a wide-angle Michelson interferometer was focused as a set of dots on the slit of a high speed streak camera, resulting in a continuous record of the fringe position as a function of time. This technique was employed to measure the particle velocity of a witness foil in a series of experiments to study the nature of detonation-driven shock waves. The present experiments demonstrated a time resolution of about 300 ps, and we believe that 20 ps resolution may be achievable with this technique. The improvement in time resolution of up to two orders of magnitude over current diagnostic techniques will be an aid in the study of several aspects of shock wave phenomena such as shock front thickness, detonation wave theory, fast relaxation at an impact plane, and fine structure in shock fronts associated with chemical reaction.
