A simple approach is proposed for determining peak frequencies, stress heights, stress lengths, full-width at half-maximum (FWHM), broadening and symmetry properties, of a composite Brillouin Gain Spectrum (BGS) which is obtained for the pulse lengths longer than the embedded stress lengths. The composite BGS is thus reconstructed in terms of extracted components. It is validated that the method is successful in determining every level of stress peaks and heights embedded in composite BGS.

提取分布式布里渊传感中增益谱的隐藏应力分量

提出了一种简单的方法来确定复合布里渊增益谱 (BGS) 的峰值频率、应力高度、应力长度、半峰全宽 (FWHM)、展宽和对称特性嵌入应力长度。因此根据提取的成分重建复合 BGS。经验证,该方法成功地确定了复合 BGS 中嵌入的各个应力峰值和高度。
