Title (EN) WAVEGUIDE INTERFEROMETER
(FR) INTERFÉROMÈTRE À GUIDE D'ONDES
Abstract:
(EN) A waveguide interferometer, particularly an optical-fiber interferometer, used to measure physical parameters, particularly changes in the optical thickness of layers in the reflective configuration, is characterized in that it contains a light source (1), a coupler (7) made on a waveguide, particularly on a fiber (6), either fibrous or planar, at least double-core, where the face of at least one core is activated, and least one waveguide core (6) is connected directly or indirectly to a signal detector (2) situated on the same side of the multicore fiber as the light source (1).
(FR) La présente invention concerne un interféromètre à guide d'ondes, en particulier un interféromètre à fibre optique, utilisé pour mesurer des paramètres physiques, en particulier des changements d'épaisseur optique de couches dans la configuration de réflexion, l'interféromètre à guide d'ondes étant caractérisé en ce qu'il contient une source de lumière (1), un coupleur (7) disposé sur un guide d'onde, en particulier sur une fibre (6), soit fibreuse, soit plane, au moins à âme double, où la face d'au moins une âme est activée, et au moins une âme de guide d'onde (6) est reliée directement ou indirectement à un détecteur de signal (2) situé du même côté de la fibre à âmes multiples que la source de lumière (1).
