Optically Recording Velocity Interferometer System for Measurement of Equation of State

摘要: 研究建立一种光学记录速度干涉仪系统（ORVIS），用于激光产生冲击波研究物质状态方程实验中的参数测量。系统时间分辨率可达几十ps，最高可测量几十km/s的速度。该系统为自由面速度和粒子速度的测量提供了一种重要的诊断手段。

Abstract: An optically recording velocity interferometer system(ORVIS) is constructed. It is applied to laserdriven shock experiments as a method for equation of state(EOS) measurement. Its best time resolution gets tens of picoseconds. It can measure the velocityof tens of kilometers per second. It is a good tool to measure free surface velocity and particle velocity.
