    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 c...

    AbstractIron-rich meteorites are significantly underrepresented in collection statistics from Antarctica. This has led to a hypothesis that there is a sparse layer of iron-rich meteorites hidden below the surface of the ice, thereby explaining the apparent shortfall. As...
