摘要
在高压电气系统中 ,磁场的检测是非常重要的。新型实用光纤磁场传感器应用了现代光通信系统中的新型磁光晶体、准直器、带尾纤的半导体激光器、耦合器等多项技术 ,使传感器不仅结构紧凑 。
In high voltage electric system,measuring the magnetic field intensity is very important.A new type of practical optical magnetic sensor applies many new technology in modern optical communication such as new Faraday rotation characterized crystal,collimator, semiconductor laser with optical fiber and coupler.It not only makes the structure compact but also has good anti seismic capability and high measuring precision.
