分布式光纤微弯应变传感器
DISTRIBUTED MICROBEND FIBER-OPTIC STRAIN SENSOR
摘要
Abstract
The distributed strain sensor has significant application in real-time measurement of strain status for large and important engineering structures such as aircraft,bridge and dam. In this paper, a quasi-distributed opticalfiber strain sensor system is set up using optical time do-main reflect technique. The local strain sensors based on a novel microbend configuration are designed and applied to measure local strains along the optical fiber. As the result of the experimental research, the microbend sensors show high sensitivity, good linearity and repeatability in certain operation range.关键词
