文摘
- •
A current measurement system based on fiber-optic curvature sensor is developed.
- •
There is a linear relationship between the output of sensor and measured current.
- •
The proposed system can measure intensity and direction of current simultaneously.
- •
Measurement accuracy is within 1% at the current range from −300 mA to 300 mA.
- •
The response of the measurement system to sine signal is satisfying.
