R. Posey et St. Vohra, An eight-channel fiber-optic Bragg grating and stimulated Brillouin sensorsystem for simultaneous temperature and strain measurements, IEEE PHOTON, 11(12), 1999, pp. 1641-1643
An eight channel fiber-optic sensor has been developed to simultaneously me
asure the strain and temperature independently using fiber Bragg gratings a
nd stimulated Brillouin scattering, The temperature and strain resolution i
s approximately 1.5 degrees C and 20 mu epsilon, and the spatial resolution
for sensing Brillouin scattering is 5 m.
