fiber Bragg grating (FBG) sensor high speed strain measurement on-line monitoring method optical fiber strain gauge
Abstract : A new technique of temperature and strain measurement using fiber Bragg grating (FBG) optical fiber sensor at high temperature in irradiation environment was proposed, in which interrogation of FBGs is carried out based on optical time-domain reflectometry (OTDR). Heating test results showed that stable temperature measurement can be done at 600°C and the reflectance of FBG can be kept constant up to 1000°C. From the strain measurement test on a cantilever, multi-point strain measurement c...
