【摘要】：為提高光纖布拉格光柵(FBG)波長解調精度,建立了"量化噪聲-波長誤差"轉換模型,并通過蒙特卡羅方法,對模型給出的誤差預測結果進行了仿真驗證。采用16位高精度模數(shù)轉換器(ADC)搭建波長解調實驗電路,誤差分析結果表明,當ADC位數(shù)從6位到16位均勻增長時,波長解調誤差從41.37 pm到0.34 pm呈指數(shù)下降,與模型計算和仿真結果相吻合。仿真及實驗均表明,所提出的"量化噪聲-波長誤差"轉換模型能準確分析量化誤差對FBG波長解調精度的影響,為FBG波長解調儀中模數(shù)轉換分辨率的選擇提供設計依據(jù)。
[Abstract]:In order to improve the wavelength demodulation accuracy of fiber Prague grating (FBG), a "quantization noise wavelength error" conversion model is set up. Through Monte Carlo method, the error prediction results of the model are simulated. 16 bit high precision analog to digital converter (ADC) is used to build the wavelength demodulation experimental circuit. The error analysis results show that the number of ADC digits From 6 to 16 bits, the wavelength demodulation error decreased exponentially from 41.37 PM to 0.34 PM, which is consistent with the model calculation and simulation results. The simulation and experiment show that the proposed "quantization noise wavelength error" conversion model can accurately analyze the effect of quantization error on the FBG wavelength resolution accuracy and the analog digital conversion in the FBG wavelength demodulator. The selection of resolution provides the basis for design.
