Paper Abstract

A distributed temperature sensing system based on optical fiber Brillouin scattering is presented in this paper. A distributed temperature sensing measurement was achieved with a BOTDR system. The light source was a narrow linewidth LD. The light from the LD was modulated by an AOM and amplified by a high gain EDFA to generate high power light pulses. So a high intensity spontaneous Brillouin scattering can be achieved. A double-pass all-fiber Mach-Zehnder interferometer was designed and used to separate Brillouin scattering from Rayleigh scattering.
