Abstract

L'invention concerne un interféromètre comportant une bobine formée d'un guide d'ondes monomode. Dans cet interféromètre, qui comporte une source de lumière 14 envoyant de la lumière à un diviseur de faisceau 9, la transmettant à un écran 12 et à un diviseur de faisceau 6, qui la transmet à un écran 11 et transmet et reçoit une partie de la lumière par un guide d'ondes monomode 1, un ou plusieurs filtres de polarisation 4, 5 sont disposés dans deux zones de superposition 142", 143" où deux faisceaux de lumière sortant par la surface de sortie de la lumière à une extrémité 100 ou 101 du guide d'ondes et sortant par la surface de sortie de la lumière située sur l'autre extrémité 101 ou 100 du guide d'ondes se superposent. Application notamment aux interféromètres de mesure de vitesses angulaires.
