提出了一种基于布里渊增益谱的测量光纤拉伸和压缩应变变化的方法。该技术被应用于表征弯曲槽型光纤电缆中的光纤应变。光纤带包含四根光纤，每根光纤通过电缆绞合。当电缆弯曲时，光纤中会产生两种类型的应变。从实验结果中发现，由纤维带沿着其长度的伸长和压缩引起的第一应变急剧减小，而由纤维带在其平面内弯曲产生的第二应变保持不变。>
A technique based on Brillouin gain spectroscopy is proposed to evaluate tensile and compressive strain variation in optical fibers. This technique is applied to characterize fiber strain in bent slot-type optical-fiber cables. Fiber ribbons containing four optical fibers each are stranded through the cable. When the cable is bent, two types of strain are created in the fiber. It was found from experimental results that the first strain, which was induced by the elongation and compression of the fiber ribbon along its length, was drastically reduced, while the second strain, which was created by bending the fiber ribbon in its plane surface, remained. >
