【摘要】 为满足在特殊的环境条件下对冲击波速度、飞片速度等冲击波物理参数的精密测量要求 ,开发了一种快响应光纤探针技术。该光纤探针由一根一端镀膜的梯度石英光纤和一根金属套管构成。在测量爆轰波、飞片和冲击波到达时间的实验中 ,可达到纳秒甚至亚纳秒的时间响应。实验证明该技术是一种可靠的、高时间分辨率的测试手段更多还原

【Abstract】 A fast rise time fiber optical pin has been developed for measuring shock wave velocity, flyer velocity etc in special environment. The pin consists of a graded index optical fiber(one end coated with metal) and a metal capillary. The intrinsic rise time of signals obtained from detonation experiments, flyer experiments and shock wave experiments is less than one nanosecond, indicating such a pin is reliable and high time resolved for measurement.更多还原
