Based on the temperature dependence of the intensity of Brillouin scattering in optical fiber, a distributed optical fiber temperature sensing experimental system with Brillouin OTDR configuration was presented. In this system, a narrow line width LD was used as a light source. The output of LD was modulated into light pulses by an AOM. After amplified by an EDFA the light pulses were coupled into the test fiber to generate backscattering signal. A double-pass Mach-Zehnder interferometer was… CONTINUE READING
