PDV + VISAR velocimeter summary
Our modular and compact velocimeter combined up to 4 slots PDV and/or VISAR. It offers excellent resolutions (time and speed) on a velocity measurement. See our demo during “les 7e journées VH” organized by the CEA/CESTA and the GDR ACO-CHOCOLAS (Gramat, 6-8 October 2022).
– Best speed resolution in the range of 0-20 km/s with our PDV slots. PDV can measure both interfaces, projectiles and debris speeds.
– Best temporal resolution in the range of 0-2 km/s with our VISAR slots. VISAR is the only technology allowing accurate detection of elastic wave precursors.
