Abstract

A multicore fibre Fabry-Perot-based strain sensor interrogated with tandem interferometry for bend measurement is described. Curvature in two dimensions is obtained by measuring the difference in strain between three co-located low finesse Fabry-Perot interferometers formed in each core of the fibre by pairs of Bragg gratings. This sensor provides a responsivity enhancement of up to 30 times that of a previously reported fibre Bragg grating based sensor. Strain resolutions of 0.6 ne/Hz1/2 above 1 Hz are demonstrated, which corresponds to a curvature resolution of ~0.012 km-1/Hz 1/2. © The Institution of Engineering and Technology 2006.
