Paper Abstract

A novel optical fibre rotation sensor which incorporates a multimode fibre storage loop inside a conventional Sagnac interferometer and utilizes a low coherence source has been described . The technique increases the number of transits the light makes around the sensing loop, thus enhancing the rotational sensitivity. The signal sensitivity has been compared with that of an optimised Sagnac interferometer and experimental results for the 10m and 20m multimode fibre loops are presented.
