摘要

    摘要
  • 摘要: F-P标准具的特性易受温度影响，温度变化时，其透射峰会发生漂移，将其应用于光纤光栅波长解调时，温度波动会给波长解调精度带来影响。分析了F-P标准具的温度特性对光纤光栅波长解调精度的影响程度，并分别采用温度稳定性为1.5 GHz和3 GHz的F-P标准具进行了稳定性和重复性实验。实验结果表明：光纤光栅传感器的中心波长不同，由F-P标准具的温度特性产生的解调误差也不同；采用2种F-P标准具测得的稳定性误差最大值分别为0.528 pm和0.676 pm，重复性误差最大值分别为1.77 pm和2.01 pm。
    Abstract: The characteristics of Fabry-Perot(F-P) etalon can be easily affected by temperature, the transmission peaks of F-P etalon drift with the fluctuation of temperature, and when F-P etalon is applied in the fiber Bragg grating(FBG) wavelength demodulation, the fluctuation of temperature may cause wavelength demodulation error. The impact of F-P etalon temperature characteristics on the FBG wavelength demodulation accuracy was analyzed, and the stability experiment and repeatability experiment were carried out using F-P etalons with thermal stabilities of 1.5 GHz and 3 GHz respectively. The analysis and experimental results show that the standard deviation of the demodulation error which is generated by the temperature characteristics of the F-P etalon is different if the center wavelength of the FBG sensor is different; the maximum stability errors obtained by two F-P etalons are 0.528 pm and 0.676 pm, and the maximum repeatability errors are 1.77 pm and 2.01 pm respectively.
