摘要：

An eight channel fiber-optic sensor has been developed to simultaneously measure the strain and temperature independently using fiber Bragg gratings and stimulated Brillouin scattering, The temperature and strain resolution is approximately 1.5 degrees C and 20 mu epsilon, and the spatial resolution for sensing Brillouin scattering is 5 m.
