Abstract

A method of discriminating between temperature and strain effects in fibre sensing using a conventionally written, in-fibre grating is presented. The technique wavelength information from the first and second diffraction orders of the grating element to determine the wavelength dependent strain and temperature coefficients, from which independent temperature and strain measurements can be made. The authors present results that validate this matrix inversion technique and quantify the strain and temperature errors which can arise for a given uncertainty in the measurement of the reflected wavelength.
