| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an optical fiber sensor cable capable of precisely measuring temperature change. SOLUTION: Such an optical fiber sensor cable is provided that an optical fiber is attached to strip state tension member having higher linear expansion coefficient than that of the optical fiber, and a fixing part being integrated so as to directly contact the optical fiber with the tension member along the longitudinal direction of the tension member continuously or intermittently is provided. Temperature in an installation environment is measured from the amount of frequency shift of Brillouin scattering light accompanying with temperature change. COPYRIGHT: (C)2009,JPO&INPIT |
