摘要
介绍了高灵敏度光纤微弱磁场传感器的软件解调信号方法,其结果使传感器测量精度达到1 nT, 单位带宽最小探测磁场达到2.86×10-10 T/Hz1/2,动态范围达到60 dB。该方法对弱磁探测技术及干涉型光纤传感器的研究十分有用。
In this paper, a signal demodulation method by software for high sensitivity fiber optic sensor of magnetic field is introduced. The measure pricision of the sensor is 1 nT, the minimun detectable field per unit bandwidth is 2.86×10-10 T/Hz1/2 and the dynamic range is 60 dB for the sensor. This work is very useful for detecting weak magnetic field technology and the research of interferential fiber optic sensors.
