    Abstract

    A framing-imaging velocity interferometer system for any reflector (VISAR) for measuring the integrity, speed dispersion and planarity of a flyer is developed. Based on the existing line-imaging VISAR, a smaller velocity-per-fringe constant is selected for higher velocity resolution, and a framing camera is used as a substitute for a streak camera to capture the two-dimensional (2D) interferograms at different time. Full-field velocity map is provided with a spatial resolution of 5 μm and a velocity sensitivity of 15 m/s. The technique is employed to measure a two-dimensional spatial velocity field of Cu (or Al) foils flyer driven by a pulse laser, and to reveal the continuous evolution of flyers. These results demonstrate that the framing imaging VISAR can be a valuable addition to the suite of diagnostics for the flyer planarity study.
