fiber-optic gyroscope: An instrument for measuring rotation rate, in which light from a laser or light-emitting diode is split into two beams which travel in opposite directions around a coil of optical fiber and recombine to generate interference fringes whose shift is a measure of the rotation rate of the coil. 2, record 1, English, - fiber%2Doptic%20gyrometry

Gyrométrie optique [...] Considérons un observateur [...] se trouvant à bord d'un laboratoire (ou d'un véhicule) en mouvement par rapport à l'espace absolu. Deux procédés s'offrent à lui pour mesurer la rotation instantanée de ce laboratoire : la mécanique rationnelle et l'optique. Mécanique rationnelle : par l'existence des forces d'inerties [...] cette voie conduit à la réalisation de gyromètres mécaniques [...] Optique : cette voie, par l'influence de la rotation du laboratoire (et par la suite des instruments utilisés) sur l'interaction instrument-lumière, conduit à la réalisation des gyromètres à fibres optiques et à celle des gyromètres laser. 2, record 1, French, - gyrom%C3%A9trie%20%C3%A0%20fibres%20optiques
