Quasi-distributed Temperature Sensing with Enhanced Measurement Range Using OFDR and Weak Reflectors
We demonstrate a quasi-distributed temperature sensor with optical frequency domain reflectometry (OFDR) and weak reflector array. A temperatrure resolution of 0.3°C is achieved with large measurement range.
