Abstract
A temperature distribution measurement system includes an optical fiber, a laser light source optically connected to the optical fiber, a photodetector configured to detect light backscattered in the optical fiber, and a temperature distribution measurement unit configured to perform correction calculation using a transfer function on a measured temperature distribution obtained from an output from the photodetector. The temperature distribution measurement unit acquires an actual temperature distribution in a location where the optical fiber 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.
