Title:

TEMPERATURE MEASUREMENT DEVICE, TEMPERATURE MEASUREMENT METHOD, AND TEMPERATURE MEASUREMENT PROGRAM

Document Type and Number:

WIPO Patent Application WO/2018/211634

Kind Code:

A1

Abstract:

This temperature measurement device is provided with: an optical fiber disposed along a prescribed path and provided with two sections that are located before and after a prescribed section and in which the temperature distribution is equal; a light source for causing light to enter the optical fiber; a temperature measurement unit which measures the temperature distribution in the drawing direction of the optical fiber on the basis of backscattered light from the optical fiber; and a correction unit which makes a correction to the temperature distribution measured by the temperature measurement unit in the prescribed section, using a Stokes component and an anti-Stokes component contained in the backscattered light from the two sections.
