摘　　要：基于相位型光纤法 珀应变传感器的基本原理 ,分析了实际光源光谱分布对传感器的影响 ,通过理论推导及模拟仿真、发现了传感器输出存在的周期性突跳现象 ,并提出了减小这种周期性突跳的方法 ,设计了一套实验系统对此进行了验证。Based on the principle of Fabry-Perot, the affect of Gaussian spectrum of light source on the fiber optical Fabry-Perot strain sensor was analyzed. A periodic jump of output was discovered by theoretical simulation. Solution of decreasing this affect was presented. Experimental setup was designed to prove the analysis, and comparison experiment was made. The experimental results show that the theory and experiment results are coincident with each other.
