Crump, Jr, O B; Stanton, P L

This report describes a new VISAR (velocity interferometer system for any reflector) built for Sandia Explosive Projects and Diagnostics Division 2514. The system incorporates push-pull signal processing, which reduces sensitivity to target self-light and simplifies data reduction. The system consists of two push-pull VISARs with two modes of operation. Each VISAR may be used independently to track separate targets or separate points on a used independently to track separate targets or separate points on a common target, or they may be used to track the motion of a single point. The latter redundant measurement is used to resolve the velocity jump ambiguity in shock-wave experiments. 6 refs., 14 figs.
