Magneto-optic current sensor using a highly-linear birefringent optical fibre

摘要: Current sensing utilising a highly-linear birefringence (HiBi) fibre has been investigated. The research is aimed at developing practical device which will be free from the noise caused by environmental disturbances. principle of sensor based on resonance nature Faraday coupling in HiBi fibre, where constructive between eigenmodes only occurs when magnetic field periodic with period equal, to close, beat length. characteristics optical and its use as current presented.
