Gyrométrie par laser. Le principe de fonctionnement des gyromètres laser est fondé sur l'exploitation de la condition (nécessaire) de résonance de la cavité optique utilisée; [...] Gyromètre laser. [...] L'appareillage comporte une partie optique [...] et une partie électronique [...] Trajet optique. Il est de forme triangulaire [...] ou carrée. La forme triangulaire ne nécessite que trois miroirs, la forme carrée conduit à un facteur géométrique S/p [...] plus favorable.
