摘要： A fiber optic displacement sensor includes a flexural disk assembly affixed to a mounting post that extends from a support base that is enclosed by a housing. Spiral wound optical fiber coils are mounted on opposite sides of the flexural disk with optical fiber leads extending from both the inner and outer diameters of the optical fiber coils and being optically coupled together to form an interferometer. An inertia ring connected to the periphery of the flexural disk has a plurality of peripheral slots therein for routing the optical fiber leads from the optical fiber coils to other components in the housing. The slots in the inertia ring are arranged to allow differing lengths of fiber to be wound circumferentially in different depth slots to accommodate mismatches in optical fiber lead lengths.

摘要： A fiber optic sensor includes a housing having first and second end plates with a sidewall extending therebetween with the sidewall having an inwardly facing groove. A flexural disk having a central passage therethrough has an outer edge portion mounted in the inwardly facing groove in the housing. The flexural disk has a stepped thickness that is thinner at the outer edge portion than at a region spaced apart from the housing. A first fiber optic coil is mounted on a first side of the flexural disk in the thicker region of the flexural disk, and a second optical fiber is mounted on a second side of the flexural disk opposite the first fiber optic coil. The first and second fiber optic coils are optically coupled together by a fiber optic coupler to form an interferometer that produces an output signal in response to axial acceleration of the flexural disk.
