A method and apparatus for reducing the thermal induced errors in an IFOG system. The apparatus including a highly thermally conductive material configured to encapsulate a waveguide of an interferometric fiber optic gyroscope (IFOG). The highly thermally conductive material more evenly distributes thermal changes encountered by a sensing coil of the IFOG thereby substantially reducing errors in the IFOG system.
L'invention porte sur un procédé et appareil visant à réduire les erreurs thermo-induites dans un système de gyroscope à fibre optique interférométrique (IFOG). L'appareil comprend un matériau hautement thermoconducteur configuré de façon à encapsuler le guide d'ondes d'un gyroscope à fibre optique interférométrique. Ledit matériau répartit plus uniformément les variations thermiques auxquelles le gyroscope à fibre optique interférométrique est soumis, ce qui permet de réduire les erreurs.
