Abstract

L'invention a trait à un gyrolaser annulaire destiné à mesurer une rotation autour d'un axe d'entrée, comportant un corps contenant une cavité polygonale formant un trajet en boucle fermée parcouru par deux faisceaux tournant en sens opposé, un miroir étant disposé à chaque angle de la cavité pour réfléchir les faisceaux, le corps du gyro présentant une forme polygonale dans laquelle deux cotés opposés sont nettement plus longs que les autres cotés qui sont petits afin de former un long corps étroit.
