Abstract
A fibre optic gyroscope including a fibre optic loop, a radiation source for generating a broadband signal, splitting means for splitting radiation from the source into two components and inserting them into the loop in clockwise (CW) and counter clockwise (CCW) directions, recombining means for recombining the components interferometrically to give an indication of rotation rate of the loop, characterized in that there is further provided amplification means for amplifying both components travelling within the loop.
