【 摘 要 】

The paper presents the diagnostic system for velocity measurements in laser- driven equations of state experiments. Two Mach-Zehnder line-imaging VISAR-type (velocity interferometer system for any reflector) interferometers form a vernier measuring system and can measure velocity in the interval of 5 to 50 km/s. Also, the system includes a passive channel that records target luminescence in the shock wave front. Spatial resolution of the optical layout is about 5 μm.
