摘要：An acoustic sensing system includes, an optical fiber, a plurality of pairs ofreflectors distributed along the optical fiber at specific areas where acoustic energy datais sought, a source of coherent radiation in operable communication with the optical fiber,
and a detector in operable communication with the optical fiber configured to detect adifferent wavelength of coherent radiation reflected from each of the plurality of pairs ofreflectors including a portion of the coherent radiation reflected from the reflectornearer the detector after having reflected from the reflector further from the detectorthat define one of the pairs of reflectors.
