The authors report on the simultaneous measurement of temperature and strain in a single optical fibre. The measurements were made using a combination of a fibre Bragg grating element and a Brillouin scattering interrogation system, operating in different optical wavelength regimes, to determine the two parameters. The system has the potential to provide quasi-distributed determination of strain and temperature along a fibre.
