摘　　要：设计了一种微型光纤光谱仪,以光纤布喇格光栅作为参考信号,用F-P滤波器进行波长解析。研究了分段校准F-P滤波器非线性和参考信号波长值的测定方法。将参考信号波峰功率下降6dB选取波形峰值两侧的特征点来确定其波长值,该方法具有较好的波长稳定性,能使微型光谱仪程序中使用的参考信号波长值与外部精确实测值保持较好的一致性。Using fiber Bragg grating as reference signal and F-P filter as wavelength resolution, micro fiber spectrometers is designed. The calibration method of F-P filter nonlinear characteristic and wavelength deter- mination of reference signal have been studied. It pointed out that the reference signal power drops 6dB the peak select the feature points on both sides of the waveform to determine its peak wavelength value, with better wavelength stability. The makes reference signal wavelength values used by the program of micro fiber spectrometer and the exact value of the external measured to maintain good consistency.
