摘要

本文采用沿三根光纤分布的24根光纤布拉格光栅，对炸药带非对称加载的金属圆柱体进行了动态光学应变测量。与较慢的电应变计相比，100 MHz色散光谱仪显示的共振没有任何电磁扰动。

Dynamic Strain Measurements by Fiber Bragg Gratings and a 100 MHz Dispersive Spectrometer

We present dynamic optical strain measurements on a metallic cylinder asymmetrically loaded by explosives bands using 24 fiber Bragg gratings distributed along three fibers. The 100 MHz dispersive spectrometer reveals resonances without any electromagnetic perturbations compared to slower electrical strain gauges.
