针对光纤电场和磁场传感器中传感信号模拟检测方法的一些不足，设计实现了一种数字检测方法，详细讨论了该方法的基本原理和数字检测电路的软在件设计。实验表明，该方法具有较好的线性性质。
Aiming at some shortages of the analog signal detection method in optical fiber electric field and magnetic field sensor, a digital detection method is designed and implemented. The basic principle of this method and software design of digital detection circuit are discussed in detail. Experiments show that this method has better linearity.
