We report the first use of a multicore fibre incorporating fibre Bragg grating strain sensors in each core as a fibre optic pitch and roll sensor. A length of four-core fibre supported at one end forms a cantilever. The differential strains between opposite grating pairs depend on the fibre's orientation in pitch (in the vertical plane) and roll (azimuth) with respect to gravity. Resolutions of ± 2° in roll and ± 15° in pitch were measured. © 2004 IOP Publishing Ltd.
