用于激光驱动冲击波诊断的成像型VISAR设计

Design of an imaging VISAR for diagnosing shock waves with laser driven

利用激光驱动冲击波是高压状态方程研究的主要手段之一,一般利用扫描光学高温计(SOP)对冲击波进行诊断,但SOP存在的靶场干扰、无法实现弱冲击波测量和状态方程绝对测量等缺陷。为解决这些问题,提出了一种用于激光驱动冲击波诊断的双灵敏度成像型任意反射面速度干涉仪(VISAR)设计,并给出了VISAR各组成部分的技术要求。

One of important methods to experimental study high-pressure equation of state was driving shock waves by laser,the streaked optical pyrometer（SOP） was usually to diagnose shock waves in this way.However,diagnosing shock waves by SOP was deficient.For example,it′s difficult to eliminate the light come from target chamber,it＇s difficult to measure the weak shock waves and realize absolute measurement of equation of state.In order to resolvethe question,we advance the design of an imaging double-sensitivity velocity interferometer system for any reflector（VISAR） and detailed technique requirement in this article.
