基于AWG的耐高温长周期光纤光栅应变监测信号解调技术研究
Research on Strain Signal Interrogation Technology of High-Temperature Long-Period Fiber Grating Based on AWG
摘要
Abstract
One of the strain signal interrogation technology of high-temperature long-period fiber grating was studied. First, the fabrication method and high temperature performance of this high-temperature long-period fiber grating were analyzed and tested,and based on Arrayed Waveguide Grating( AWG)device,a novel strain signal interrogation method was researched with cantilever of equal strength. The experimental results verified that the signal interrogation technology based on AWG has many advantages, such as simple structure, innovative, reliable performance, and so on. Curve reconstruction method of the test data were discussed in the process of signal interrogation based on AWG, and temperature-strain cross sensitivity compensation algorithm named data fusion algorithm was experimentally studied, which obtained obvious effect on temperature compensation finally.关键词
