| 摘 要： | 提出了一种利用布里渊光纤环形腔移频技术实现分布式光纤布里渊传感的方法.该方法基于布里渊光时域分析法原理,将一束单纵模运转激光器输出的激光分为两束;一束光入射布里渊光纤环形腔中产生窄线宽的受激布里渊散射光作为斯托克斯光,另一束光经过低频相位调制后作为泵浦光;斯托克斯光和泵浦光分别相向入射进入传感光纤,通过测量布里渊谱得到...

| Abstract: | A novel method to implement distributed fiber optic Brillouin sensing was proposed,using the frequency shifting technique via a Brillouin fiber optic ring cavity.The method is based on the Brillouin optical time-domain analysis(BOTDA) principle that a laser beam from single-longitudinal model lasing is divided into two beams;one beam is launched into the Brillouin fiber optic ring cavity to generate the stimulated Brillouin scattering wave of narrow bandwidth as the Stokes wave,the other one is taken as the... |
