Title: Fiber-Optic Brillouin-Based Discriminative Sensing of Strain and Temperature
Abstract: Fiber-optic distributed sensing systems based on Brillouin scattering have been regarded as powerful tools to monitor distributed strain or temperature in smart materials and smart structures. So far, different techniques (i.e. time-domain and correlation-domain) are used to resolve the sensing location, while their sensing mechanisms are all based on the linear dependences of Brillouin frequency shift on strain and/or on temperature. This common mechanism results in a heavy trouble for any of above techniques in discriminating the response to strain from that to temperature by using a single piece of fiber. This presentation will demonstrate two individual methods to realize discriminative sensing of strain and temperature. One is based on multiple acoustic resonance peaks in a specially-designed optical fiber and the other on Brillouin-generated dynamic acoustic grating in a polarization maintaining optical fiber. Complete discrimination of strain and temperature using the latter method will be theoretically and experimentally demonstrated. Distributed discriminative sensing of strain and temperature based on correlation-domain continuous-wave technique will also be introduced.
