Abstract: The present invention relates to methods and apparatus utilizing distributed temperature sensing (DTS) to monitor the temperature of a cured-in-place pipe liner to determine if proper curing temperatures and times are achieved. More particularly, an optical fiber is placed between the pipe and the liner running the entire length of the liner. The optical fiber is coupled to a DTS unit. During curing of the liner, the DTS unit sends light pulses down the fiber from one end and detects the characteristics and time delay of light backscattered to the unit. The characteristics are indicative of the temperature of the optical fiber, while the delay is indicative of the round trip time of the light within the fiber, and thus the distance from the DTS unit from which any particular backscatter signal originated.
