An optical fiber temperature distribution measuring device includes: an optical fiber as a sensor; a calculation control unit for measuring a temperature distribution along the optical fiber based on an intensity ratio between Stokes light and anti-Stokes light of backward Raman scattered light from the optical fiber; and a temperature correction unit for correcting the temperature distribution by using temperature dependence of a loss difference between the Stokes light and the anti-Stokes light. |
