ABSTRACT:
A fiber optic sensor for sensing the presence of an analyte has a plurality of optical fibers each of which has at least one analyte sensing segment and one or more low loss lead portion, where the optical fibers are disposed on the periphery of a fiber carrier. The analyte sensing segments may be disposed in an offset relationship to provide continuous detection over a desired distance or they may be spaced apart to provide detection at selected locations. More than one set of optical fibers with sensing segments may be combined to provide detection of multiple analytes. Multiple fiber carriers allow each segment or the grouped sets of segments to be coupled together over a distance either in offset relationship or in spaced apart relationship.
