| Abstract: | The common optical fiber electric current sensor is based on Faraday Magnetism-Photo Effect and is mainly used in detecting high-voltage strong electric current,and the optical fiber used is single-mode and polarization-ensured.A intensity modulated optical fiber sensor is designed,which makes use of the tiny bend effect to measure small electric current.With testing the change of energy of output light of optical fiber,we can measure the small electric current. |
