摘要
提出了一种以可调谐滤波器实现波长扫描、以标准具实现波长标定的有源光纤光栅传感器波长解调方法,并搭建了相应的解调系统。对所提出的解调方法的可行性及解调系统的测量精度与稳定性进行了实验验证。结果表明,该方法可以准确地测量有源光纤光栅的光波长;解调系统在1533~1550 nm波长范围内的解调精度高于6 pm,测量波动范围在±5.7 pm之间。
Abstract
A wavelength demodulation method for the active fiber grating sensor is proposed. A tunable filter is used for wavelength scanning, and an etalon is used for wavelength calibration in this method. The corresponding demodulation system is set up. The feasibility of the demodulation method and the accuracy and stability of the demodulation system are verified experimentally. The results show that the proposed method can measure the wavelength of the active fiber grating accurately. When the wavelength range is from 1533 nm to 1550 nm, the accuracy of the demodulation system is higher than 6 pm, and the fluctuation range is within ±5.7 pm.
