Abstract:In this Letter, two gyro outputs containing identical rotation rates are produced by a twin-peaks light source with peak wavelengths of 1530 nm and 1560 nm. We demonstrate that the two outputs’ ratio
κ
can compensate for the temperature-induced scale factor drift in an interferometric fiber-optic gyroscope (IFOG). When the temperature ranged from

to 50°C, the scale factor drift after compensation was about 30 times less… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
