ABSTRACT:
A fibre optic gyroscope is provided with temperature compensation means which impose on the coiled fibre a thermal coefficient of expansion which is selected to be approximately equal in value to the refractive index temperature coefficient of the fibre, thereby reducing the Scale Factor temperature coefficient. The temperature compensation means may be in the form of a former element or a coating applied to the fibre.
