Abstract

The study of high-pressure sound velocity is an important part of shock wave physics, and the study of ultra-high pressure sound velocity of iron is of great significance to many research fields such as geophysics, solid state physics, and crystallography. At present, the measurement of sound velocity is usually carried out by the catch-up sparse wave method and windowed VISAR technology, which is complex in structure and not highly adaptable. In particular, for the ultra-high pressure sonic velocity measurement of metals, it is limited by the loading platform and window materials and cannot realize the high temperature and high-pressure environment of the earth's inner core. In this paper, the sound velocity measurement of iron under high temperature and high-pressure environment (78 GPa) is realized based on the two-stage light gas cannon experimental platform. The side-side sparse wave method was used to establish a coupling model of high-spatially resolved optical group and fiber bundle. A multiplexed all-fiber laser interferometry velocity measurement system (DISAR) was built, and the spatial resolution was better than 20 μm. In this paper, we will provide a feasible route for a method for measuring the high spatiotemporal resolution velocity.

摘要

高压声速研究是冲击波物理的重要组成部分，铁的超高压声速研究对地球物理、固态物理和晶体学等诸多研究领域具有重要意义。目前，声速测量通常采用追赶稀疏波法和带窗口的VISAR技术，其结构复杂且适应性不强。特别是对于金属的超高压声速测量，受到加载平台和窗口材料的限制，无法实现地球内核的高温高压环境。本文基于二级轻气炮实验平台实现了高温高压环境（78 GPa）下铁的声速测量。采用侧面稀疏波法建立了高空间分辨率光学组与光纤束的耦合模型。构建了复用全光纤激光干涉测速系统（DISAR），空间分辨率优于20μm。本文将为一种高时空分辨率速度测量方法提供可行途径。
