Brillouin backscattering spectra for PMMA, fused silica, and soda lime glass

This data set contains Brillouin backscattering spectra used in publication "Accuracy of simultaneous refractive index and phonon velocity estimation using Brillouin backscattering in the platelet geometry". The ZIP archive contains text files that contain the raw Brillouin spectra presented as two columns: 1/ frequency in GHz 2/ photon count.本数据集包含用于发表于论文《平板几何下利用布里渊背向散射（Brillouin backscattering）同时估算折射率与声子速度的精度》中的布里渊背向散射光谱。该ZIP压缩包内存储有若干文本文件，其中包含以两列形式呈现的原始布里渊背向散射光谱数据：1/ 频率（单位：吉赫兹（GHz））；2/ 光子计数。
