| Abstract: | This paper expatiates on the theory of a distributed infrared optical fiber Raman temperature sensor on the infrared double wavelength with a Er doped waveguide amplifier. For restraining the amplifier ASE increase and the temperature excursion accumulation and the anti-Stokes back-scattering intermingling with the Rayleigh back scattering, it thinks over what to demodulate on the basis of the newly acquired temperature curves and two pending standard temperature curves. It advances the temperature precision to ±0.1 ℃ and system stability, it reduces the cost and has the consistency of theory and test. |
