摘要

摘要: 对用光纤探针测量飞层前界面微喷、微层裂等现象的机理进行了分析，设计了光纤探针与瞬态粒子场全息照相技术联合测量泰安药柱加载下铅飞层的前界面状态的实验。实验结果表明，光纤探针的测量结果与瞬态全息照相的结果相吻合，说明利用光纤探针可以对微喷粒子场进行有效探测，是一种很有发展潜力的测试技术。

Abstract: The interaction mechanism was analyzed between ejecta micro-spalling and fiber-optic pins. The fiber-optic pins and pulsed in-line particles holography were applied in the diagnosis of ejecta and micro-spalling from shocked metal surface. The experimental results from fiber-optic pins are in agreement with those from pulsed in-line particles holography. In other words, the signals of fiber-optic pins illustrated the process of micron-scale fragments ejected from shocked metal surfaces. Due to the fact that fiber-optic pins have simple structures and the full-range of measurement from the zone of low areal density to the zone of thick metal sample, it is potentially effective in detecting the phenomena of shocked metal surfaces.
