Experimental Study of Temperature Correction on Single-Mode Sleeve Fiber for Distributed Strain Monitoring

Abstract

Because of the temperature effect of the distributed strain observation, it is not easy to analyze the real strain in tested data. Experiments of fibers under different temperatures and force conditions are carried out. The bare fiber, Φ 0.9 SM and Φ 2.0 SM single-mode sleeve fibers are chosen in the experiment scheme. It was found that the temperature effect of the distributed strain is independent with the force condition. The additional strain of fibers under the stress and different temperatures are discussed. For practices using, temperature correction equations on single-mode sleeve fiber are proposed to reduce the temperature effect.
