A novel line-imaging velocity interferometer was developed and implemented, which is suited for small scale specimens shock wave experiments. Using a combination of fiber array, electron-multiplier phototube and digital oscilloscope for recording a comb fringe signal, the velocimeter was capable of 1 ns time resolution and 86 μm spatial resolution. Velocity measurement for Al flyer driven by laser was implemented to test this system. The results showed that the flyer has a 20 ns acceleration history and 14.8 mrad planarity. The experiment confirmed that the new system is valuable for temporal-spatial shock diagnositics.
