| 摘 要： | 光纤光栅反射波长即光纤光栅Bragg波长的解调技术是光纤Bragg光栅(Fiber Bragg Grating,FBG)实用化的关键技术。针对基于可调谐法布里-珀罗(Fabry-Perot,F-P)滤波器的光纤光栅解调系统,在直线插值法的基础上,提出了二次曲线修正的光纤光栅Bragg波长解调算法,并做了实验研究,达到了提高光纤光栅Bragg波长解调精度的目的。

| Abstract: | The optical fiber diffraction grating reflection wave length is the optical fiber diffraction grating Bragg wave length demodulation technology is the optical fiber Bragg diffraction grating (Fiber Bragg Grating, FBG) the practical key technologies. In view of based on might harmonious Pabri - the amber Luo (Fabry-Perot, F-P) filter optical fiber diffraction grating demodulation system, in the straight line interpolation foundation, propose the conic section revised the optical fiber diffraction grating Bragg wave length demodulation algorithm, and has done the experimental study, had achieved increased the optical fiber diffraction grating Bragg wave length demodulation precision the goal. |
