Abstract
The present invention is directed toward an interferometric sensor that permits the simultaneous measurement of a change in more than one environmental condition. The interferometric sensor comprises an optical fiber and a plurality of sensing regions positioned in an operable relationship to the optical fiber. Each sensing region has partially reflective boundaries and produces an interferometric signal.
Claims15
An interferometric sensor arrangement comprising:
- an input/output optical fiber positioned in an operable relationship to a plurality of bulk sensing mediums having physical and optical properties wherein the physical and optical properties of the bulk sensing medium change in response to an environmental condition;
- wherein each bulk sensing medium is extrinsic to the input/output optical fiber;
- and wherein each bulk sensing medium produces an interferometric signal.
