Abstract

Abstract

A line-imaging velocity interferometer was developed and implemented, which is used for laser-driven-flyer velocity measurement with high temporal and spatial resolution. Based on VISAR and ORVIS, this system reshapes the probe laser to line light on the target, collects scattered reflection by imaging lens, uses a wide angle Michelson interferometer to produce a comb fringe as velocity information carrier and records the image using streak camera. The velocimeter is capable of 50 ps temporal resolution and 20 μm spatial resolution. Velocity measurement for Al flyer driven by laser was implemented to test this system. Very intuitive image records and data processing results provided a large number of valuable information, confirming that the velocimeter is adequate for laser driven flyer
