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.

摘要： A distribution optical fiber sensor system measures distortion and temperature of a structure with a high spatial resolution. The system has an optical fiber on an object to be measured. A light source emits a first pulse light having a pulse width longer than a transient response of an acoustic phonon and a second pulse light after a time interval during which vibration of the acoustic phonon is maintained thereby supplying the pulse lights to the optical fiber. A detector detects scattering gain spectra of a Brillouin-scattered light created in the optical fiber by the second pulse light at intervals corresponding to twice the time obtained by equally dividing the pulse width of the second pulse light. A controlling/calculating unit calculates distortion and/or temperature based on the scattering gain spectra for sections of the optical fiber corresponding to the scattering gain spectra at the respective time intervals.
