Abstract

Distributed temperature sensing (DTS) is demonstrated using an enhanced scattering optical fiber (ESF). The temperature measurement is based on measuring the intensities of the backscattered light with two broadband lights. The spectra of the broadband light partially overlap with the backscattered spectrum of the ESF. Since the spectrum of the ESF shifts with temperature, the intensities of the backscattered light will change. The temperature coefficients of the system are -0.011 dB/°C and 0.022 dB/°C. Using the system, a low cost and high speed DTS system can be accomplished.
