摘要
本文提出了一种新型的高压电流光纤传感器 ,该系统由具有相位压缩原理的Sagnac干涉仪光路构成 ,与通常的干涉仪相比该系统的动态测量范围扩大数百倍 ,而且系统不受外界缓变量的影响 。
A novel high voltage current fiber optic sensor is proposed. It is made up of the phase compress Sagnac interferometer. Compared with the common interferometers, this system has a large dynamic range extended thousands times, and is out of the effect of slow circumstance variables. The phase shifted technology makes the interferometer work at orthotronic interference state.
