Instantaneous Area Based Online Detection of Bend Generated Error in a Raman Optical Fiber Distributed Temperature Sensor
IEEE Sensors Letters(2017)
摘要
Error-free temperature measurement by Raman scattering based optical fiber distributed temperature sensor (OFDTS) is possible if the sensing fiber has no sharp bend. However, in real life applications, the sensing fiber might have sharp bend that may cause discontinuity in the profiles of Raman anti-Stokes (AS) and Stokes (St) signals resulting in erroneous distributed temperature measurement by O...
