Abstract

In the paper we present an alternative configuration for an interferometric distributed optic fiber sensor which adapts a combination of Mach-Zehnder and Sagnac interferometers different from that have published before. Based on the outputs of the Mach-Zehnder interferometer and sagnac interferometer, the place where the disturbance occurs to the sensing fiber can be obtained. Detailed theoretical analysis and corresponding experiments about this configuration are presented in this paper.
