摘要
对光纤光栅传感器的光栅调谐滤波检测系统进行了理论和实验研究 ,给出了波长测量分辨率的理论表达式 ,理论计算的系统最佳波长分辨率为 0 8pm ;基于高性能的光电测量系统 ,实验测得的波长分辨率可达 2pm ,应变分辨率可达 1 7με。
The tunable grating filtering detection system of fiber grating sensor was investigated theoretically and experimentally. The theoretical expression of wavelength resolution was presented. The optimum theoretical wavelength resolution of the system is 0.8 pm. Due to the excellent performance of the photoelectric detection system, the measured wavelength resolution of sensing detection is 2 pm and the strain resolution is 1.7 μΕ in the experiment.
