摘要： A distributed optical fiber sensor uses a Brillouin scattering phenomenon to avoid manual adjustment and to measure strain and/or temperature with high accuracy and high spatial resolution. A stepwise optical light source generates an optical pulse having a stepwise distribution of intensity to increase toward the center, and a continuous light source generates continuous light on. The optical pulse is incident on a sensing optical fiber as probe light and the continuous light is incident as pump light to cause a Brillouin scattering phenomenon between the probe light and the pump light. A Brillouin time domain detector determines a Brillouin loss or gain spectrum from the light emerging from the sensing optical fiber and attributed to the Brillouin scattering phenomenon, and measures strain in and/or temperature of the sensing optical fiber in the longitudinal direction thereof based on the determined Brillouin loss or gain spectrum.
