Optical fiber gyroscope
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 … See more Two beams from a laser are injected into the same fibre but in opposite directions. Due to the Sagnac effect, the beam travelling against the rotation experiences a slightly shorter path delay than the other beam. The resulting … See more A FOG provides extremely precise rotational rate information, in part because of its lack of cross-axis sensitivity to vibration, … See more • Attitude and Heading Reference System • Hemispherical resonator gyroscope • Inertial measurement unit • Inertial navigation See more Like all other gyroscope technologies and depending on detailed FOG design, FOGs may require initial calibration (determining which indication corresponds to zero angular velocity). Some FOG designs are somewhat sensitive to … See more • Anthony Lawrence, Modern Inertial Technology: Navigation, Guidance, and Control, Springer, Chapters 11 and 12 (pages 169–207), 1998.

WebJan 31, 2024 · The Fiber-Optic Gyroscope, Third Edition. This landmark work – considered by many in the field to be THE reference on fiber-optic gyroscopes (FOGs) – provides you with a complete and thorough system analysis of the FOG and remains unmatched by any other single source. Now in its third edition, this fully updated and authoritative book: Web3 OPTICAL GYROSCOPES: FOG & RLG Both optical gyroscopes, ring-laser gyro (RLG) and fiber-optic gyro (FOG), are based on the same Sagnac effect. The RLG was demonstrated only a few years after the invention of the laser in 1960, and it is based on helium-neon (He-Ne) technology. It became very successful in the 80s and has since
