摘要：
Distributed optic fiber has been an international study issue, because of its irreplaceable advantage embodied in measurement. In this paper, sensing mechanism based on Brillouin scattering distributed optic fiber is described, the influence of strain and temperature on Brillouin frequency-shift is analyzed, and a formula is given. Furthermore an optimum design scheme for Mach-Zehnder interferometer is introduced in this system, in signal detection, double-ended detection method is adopted to realize detection of intensity and frequency-shift of Brillouin scattering signal at the same time and to shorten measuring time of system, and dual-channel Mach-Zehnder interferometer is introduced to detect signal and to filter Rayleigh light. Contrast test is implemented and better experiment result is obtained.
