Data for: Spectral Verification of the Mechanisms behind FBG-based Ultrasonic Guided Wave Detection

This data set consists of the filtered and averaged UGW data, and the extracted Gaussian fit data (UGW_fit.mat) for the Bragg wavelength and FWHM of the Bragg peak.本数据集包含经滤波与平均处理的超声导波（Ultrasonic Guided Wave，UGW）数据，以及针对布拉格峰的布拉格波长与半高全宽（Full Width at Half Maximum，FWHM）提取得到的高斯拟合数据（UGW_fit.mat）。
