TEMPERATURE DISTRIBUTION MEASUREMENT SYSTEM, TEMPERATURE DISTRIBUTION MEASUREMENT DEVICE, AND TEMPERATURE DISTRIBUTION MEASUREMENT METHOD

摘要

[Object] To provide a temperature distribution measurement system, a temperature distribution measurement apparatus, and a temperature distribution measurement method capable of easily evaluating the appropriateness of a transfer function used in correcting a measured temperature distribution. [Solving Means] A temperature distribution measurement system includes an optical fiber 24, a laser light source 21 optically connected to the optical fiber 24, a photodetector 26 configured to detect light backscattered in the optical fiber 24, and a temperature distribution measurement unit 27 configured to perform correction calculation using a transfer function on a measured temperature distribution obtained from an output from the photodetector 26. The actual temperature distribution measurement unit 27 acquires an actual temperature distribution in a location where the optical fiber 24 is laid and determines appropriateness of the transfer function by computing a difference between the measured temperature distribution after the correction and the actual temperature distribution.
