| 中文摘要 | we present a simple and practical method for the single-ended distributed fiber temperature measurements using microwave (11-ghz) coherent detection and the instantaneous frequency measurement (ifm) technique to detect spontaneous brillouin backscattered signal in which a specially designed rf bandpass filter at 11 ghz is used as a frequency discriminator to transform frequency shift to intensity fluctuation. a brillouin temperature signal can be obtained at 11 ghz over a sensing length of 10 km. the power sensitivity dependence on temperature induced by frequency shift is measured as 2.66%/k.
