| Abstract: | A distributed optical fiber sensor is designed, which is based on the principle of optical time domain reflection. The characteristics of optical fiber transmission is measured by the intensity of Rayleigh scattered light which is verified with time. The distributed fiber test system is constructed for real-time monitoring which has a good application in overhead lines. The performance of the system is tested, which verifies the measurement accuracy of the system is about ±0.5℃ with good stability. |
