Abstract

We demonstrate a novel technique to enlarge the measurement range of a correlation-based fiber Brillouin distributed sensing system using double lock-in amplifiers and a single-sideband modulator. 300-m measurement range with 20-cm spatial resolution is achieved without any optical filter.
