【摘要】 分析了匹配型光纤布拉格光栅波长移动解调方案的基本原理,构建了光功率与波长偏移量以及光功率与轴向应变、温度变化量函数关系式,绘制了其变化曲线。为波长移动解调方案的实施奠定了理论基础。最后给出了该传感实验系统的实验结果。更多还原

【Abstract】 Analyzed the theory of the wave-length-migration demodulation project of matched fiber-Bragg-gating (FBG), and constructed related equations about the luminous power versus wave-length deviant, axial strain and temperature change. And the changing curves wese drew was estahlished. Established the base theory of the implementation of the wave-length-mobile demodulation method. The result of the sensing experiment system was given.更多还原
