CA 2576978

The invention provides a method and a system for measuring a physical quantity by means of a tandem interferometer optical sensor system based on low- coherence interferometry. The system comprises a light system, a sensing interferometer and a polarization readout interferometer. The invention provides a polarization interferometer comprising a single birefringent wedge. The invention also provides for a dispersion-compensated optical sensor system. The invention also provides an interferometer sensitive to temperature that comprises a trajectory in a LiB3O5 crystal with an x-cut orientation.

L~invention concerne un procédé et un système pour mesurer une quantité physique au moyen d~un système de capteurs optiques d~interféromètre en tandem basé sur l~interférométrie à basse cohérence. Le système comprend un système lumineux, un interféromètre de détection et un interféromètre d~affichage de polarisation. L~invention met à disposition un interféromètre de polarisation comprenant un coin biréfringent unique. L~invention met également à disposition un système de capteurs optiques compensés en dispersion. L~invention met également à disposition un interféromètre sensible à la température qui comprend une trajectoire dans un cristal LiB3O5 avec une orientation de taille X.
