Abstract
L'invention consiste en un gyroscope à laser en anneau avec une compensation du signal de sortie pour les variations de puissance optique en fonction d'une fréquence dièdre. Le gyroscope comporte une cavité 20 avec un trajet fermé 30 et un agent de gain 26. Des réflecteurs 32, 34, 36, 38 produisent un déphasage dépendant du sens des ondes en polarisation circulaire, conduisant à une séparation de fréquences entre les ondes de même sens de polarisation. Un détecteur 22, 23, 48 détecte la fréquence dièdre et un processeur commande le signal de sortie en fonction des variations de la fréquence dièdre. L'invention s'applique à des gyroscopes de navigation. (CF DESSIN DANS BOPI)
