  • Apparatus and method for sensing acceleration or force using fiber Bragg grating (FBG)
    Patent number: 10976338
    Abstract: A fiber-based accelerometer (FAC) detector includes a base; first and second flexures mechanically coupled to the base; first and second masses mechanically coupled to the first and second flexures, respectively; and a fiber Bragg grating (FBG) fiber mechanically coupled to the first and second masses, wherein the first and second flexures and the first and second masses are configured to move in response to a force and/or acceleration acting upon the first and second masses to produce a compression or expansion of the first FBG fiber.
    Type: Grant
