Novel Fiber-Optic Distributed Disturbance Sensor Using a Modified Phase Generation Carrier Technique

Abstract:

Article Preview

A Mach-Zehnder interferometer based fiber-optic distributed disturbance sensor (FDDS) incorporating a modified phase generation carrier (PGC) is proposed and investigated. It is found that the slow time-varying fluctuation such as temperature variation causes the location errors. By employing a modified PGC technique that satisfies the requirements including high sampling frequency and compensation of the time delay from the long length fiber, the location errors caused by the slow time-varying fluctuation can be eliminated.
