  • Method and system for interrogating optical fibers
    Patent number: 11549860
    Abstract: A method and a system for interrogating an optical fiber includes a probe signal that has a first frequency comb at a first repetition rate (?f) injected into the optical fiber. A backscattering signal that includes the probe signal convolved with an impulse response of the optical fiber in reflection which is sensitive to at least one parameter being measured from the optical fiber is gathered. The backscattering signal is beaten with a local oscillator signal to generate a beating signal, the local oscillator signal including a second frequency comb at a second repetition rate that is offset from the first repetition rate (?f+?f) and being mutually coherent with the first frequency comb. The resulting beating signal is analysed to thereby determine the at least one parameter being measured from the optical fiber.
