Abstract
Fiber optic sensors include sensor regions in which an optical phase is modulated by an analyte to be detected. A long period fiber grating (LPG) is coupled to a coating that is arranged to selectively interact with the analyte. The resulting phase change is detected based on a transmission spectrum associated with the LPG so that analyte is detected and quantified. A plurality of such sensors is distributed along a fiber to form a sensor array that can be situated to detect analyte at a plurality of discrete regions.
