Abstract

The principle of all fiber Mach-Zehnder interferometer as an optical filter was investigated in this paper. All fiber Mach-Zehnder interferometers with single-pass and double-pass configuration were manufactured and used in the measurement of spontaneous Brillouin scattering. The separation of backscattered spontaneous Brillouin from Rayleigh with low losses was achieved effectively. With the Mach-Zehnder interferometer, a direct optical detection method was used in Brillouin OTDR, by which a new detection method for distributed sensing system based on spontaneous Brillouin scattering was proposed.
