This patent discloses a polarimetric Fabry-Perot sensor comprising a source of coherent polarized light, an optical cavity, preferably an optical fiber, capable of supporting two independent modes of that light and coated with partially reflecting material on both ends, a sensing element for detecting the external field that differentially affects the two modes, and means for measuring interference between the two modes.
