Abstract

We investigate the effect of temperature on a multicore fibre (MCF) curvature sensor. The curvature sensing element is formed from four Fibre Bragg gratings (FBGs) inscribed in a MCF. A fibre optic coupled fan-out device is used to interface the MCF to standard single core fibre optic technology. The peak positions of the FBGs are measured to determine wavelength shift as a result of the curvature induced strain on the fibre. The differential strain allows the curvature of the fibre in a plane to be extracted. The temperature sensitivities of the FBGs and the fan-out device are examined thoroughly.
