The interference on a Sagnac interferometer is proportional to the enclosed area. A looped fibre-optic coil multiplies the effective area by the number of loops.

A fibre-optic gyroscope (FOG) senses changes in orientation using the Sagnac effect, thus performing the function of a mechanical gyroscope. However its principle of operation is instead based on the interference of light which has passed through a coil of optical fibre, which can be as long as 5 kilometres (3 mi).
