  • Interferometric sensors utilizing bulk sensing mediums extrinsic to the input/output optical fiber
    Patent number: 6671055
    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.

  • Fiber optic wall shear stress sensor
    Patent number: 6426796
    Abstract: A fiber optic wall shear stress sensor is presented. The sensor comprises a floating head supported by a physical arrangement. At least one optical fiber is positioned in an operable relationship to the floating head wherein an interferometric region is formed between the floating head and each optical fiber. The interferometric region changes in response to a shear force on the floating head.
