Abstract

A method of deriving substantially independent measures of temperature and /or strain using a single anisotropic fiber Bragg grating comprises directing broadband light into an optical fiber 12 containing the grating (10a, 10b or 10c) for transmission along the fiber to the grating. An interferometer 24 is used to detecting the spectrum of the light reflected from the grating and emerging from the fiber. A PC 26 determines temperature as a function of the width of the spectrum, and/or determines strain as a function of the both the position and width of the spectrum.
