Abstract
A fiber optic fiber Fabry-Perot interferometer diaphragm sensor and method of measurement is provided. A fiber Fabry-Perot interferometer diaphragm sensor (,) includes a base (,) and a diaphragm (,) with an optic fiber (,) coupled under tension between the base (,) and the diaphragm (,). A fiber Fabry-Perot interferometer element (,) is contained within the optic fiber (,) and operates to sense movement of the diaphragm (,). In a particular embodiment, the diaphragm (,) moves in response to a pressure (P) applied to the diaphragm (,). In another embodiment, a proof mass (,) is coupled to the diaphragm (,) such that the diaphragm (,) moves in response to an acceleration (A). In yet another embodiment, a magnetic body (,) is coupled to the diaphragm (,) such that the diaphragm (,) moves in response to a magnetic field (M).
