Distributed optical fiber sensors have been developed to detect the occurrence of structural anomalies such as excessive stresses, cracks, and leaks at arbitrary locations in the facility. In this paper, we demonstrate fiber optic OFDR (Optical Frequency Domian Reflectometry) sensor to measure strain and temperature through the sensing optical fiber. A PVC pipe was prepared to show the strain measurement performance with a sensing optical fiber attached on the pipe. Also, a temperature test was performed with a sensing optical fiber located in a temperature chamber. In the results, this sensor can operate to resolve 14.2 micro strain and 1.62 degree temperature at the condition of 5 cm spatial resolution.
