| Summary: | The present invention relates to fiber optic sensors. In particular, it relates to an interferometric sensor that is capable of making simultaneous measurements for a variety of environmental conditions.
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. |
