Abstract

From the advantage and defect of current distributed optical- fiber sensors (DOFS) schemes, it could be seen that most of schemes except distributed anti-Stokes Ratio Thermometry (DART) are only possible in experiment, but unpractical. But DART is not able to be used on small and fine things especially for smart structures, because of its poor spatial resolution. As we all know that the relaxation time of Raman scattering is in the femtosecond range, and a optical pulse with width > 1 ps will not receive gain reducing, so the potential spatial resolution of DART can be smaller than 0.1 m, even 1 mm (for a pulse with width < 10 ps). Considering these, we firstly propose a novel scheme of DOFS based on spontaneous Raman back-scattering and the effect of high-order soliton, which uses time-correlated single photon counting as detector. The first-order and high-order solitons' effect in the system are theoretically investigated, and it is found that it is able to improve the spatial resolution observably by using high-order soliton in relatively short sensing distance (< 1 km). In the end, the possibility and difficulties of realizing the system based on present-day level of devices are considered.
