Abstract

We propose and demonstrate a regional selectable distributed optical sensing system based on monitoring the fiber optic length fluctuation shifting by using optical pulse correlation measurement. The measureable regions easily upgrade using by scanning of time position method and frequency sweep of pulse repetition method. These regional selected sensing techniques experimentally operated within sub-micro-epsilon level strain of resolution in monitoring fiber environment change.
