| 摘 要： | 提出了一种适用于啁啾光纤布拉格光栅CFBG(chirped fiber Bragg grating)传感器测量爆轰波速度的实验公式，该公式考虑了ASE(amplified spontaneous emission)光源的光谱、CFBG的平坦度对测量的影响；研究了CFBG的反射谱线宽与长度的理论关系，并设计了测量CFBG反射谱线宽的实验装置，从而可计算出CFBG长度。搭建了测量CFBG传感器系统常数的实验装置，并利用实验数据拟合了系统常数；用CFBG传感器测量了RDX/TNT(60/40)的旁侧爆轰波速度，与其爆速有3.4%的差异。

| Abstract: | An experimental equation of CFBG sensor for detonation velocity measurement which was based on the flatness of ASE light source and CFBG reflection spectrum, was quantitatively established for the first time. The CFBG length could be calculated by the theoretical relation between it and the CFBG reflection spectrum line-width, which was measured experimentally. The constant of the CFBG sensor was fitted by the experimental data. The side detonation-wave velocity of RDX/TNT (60/40) was measured with 3.4% error compared to the publication value. |
