摘　　要：研究了光纤电场传感器中的调制与解调技术，提出了对光源脉冲调制和对光电信号解调来抑制光电信号中噪声和补偿光功率的不稳定的方法。并将这一技术应用于单光路检测系统，获得了满意结果。The optical modulation and electrical demodulation technique are pres ented. Applying this technique to an optical fiber electric field sensor, the noise of optical and electrical signal in the detection system is controlled and the unstable optical power of light source is also compensated. The satisfaCtory result of experiment is obtained in the sensor with single optical channel.
