A Broadband Distributed Vibration Sensing System Assisted by a Distributed Feedback Interferometer

A distributed vibration-sensing system based on phase-sensitive optical time-domain reflectometry (Φ-OTDR) and distributed feedback interferometer (DFI) with broadband frequency response and high spatial resolution has been proposed and demonstrated. A couple of narrow line-width lasers w...
