Paper Abstract

As a developing novel technology recently distributed optic fiber temperature sensor has received considerable attentions. By optic fiber back spontaneity Raman dispersion phenomenon and OTDR theory, the system works. In this paper Rayleigh scattering curve demodulating anti-Stokes Raman scattering curve instead of traditional demodulation to mend SNR is adopted. And because of the differences of the two back dispersion parameter, wastage parameter and so on, signal groups grow indistinct by any demodulation method. Therefore, it is necessary for us to dispose micro-signal.
