A Fiber-Optic Voltage Sensor Based on Macrobending Structure
نویسندگان
چکیده
We propose and demonstrate an optical voltage sensing scheme based on a macrobending optical fiber in a ratiometric power measurement system. This novel approach to sensing has not been utilized before and has the advantage that the sensor involves simple fabrication compared to existing fiberoptic voltage sensors. To prove the feasibility of such a fiber-optic sensor, a sensor for a voltage range from 0 100 V is demonstrated, with a resolution of 0.5 V. The sensor is robust, linear, and shows a competitive measurement resolution. The sensor can be easily scaled to suit other voltage levels and be effectively combined with optical current sensors. & 2011 Published by Elsevier Ltd.
