Title:
温度測定装置、温度測定方法および温度測定プログラム
Document Type and Number:
Japanese Patent JP6561747
Kind Code:
B2
Abstract:
A temperature measurement device includes: an optical fiber that is arranged along a predetermined path; a light source configured to input a light into the optical fiber; a measurer configured to measure temperature distribution information in an extension direction of the optical fiber based on a back-scattering light from the optical fiber; and a corrector configured to make a filter for reducing a noise component of temperature distribution information measured by the measurer based on a difference of temperature distribution information between two different regions of the optical fiber in which a common temperature distribution is obtained, and correct the temperature distribution information by applying the filter to the temperature distribution information.
