abstract = "Fiber optic pH sensors, based on evanescent-wave spectroscopy, are demonstrated for short length distributed chemical sensing in civil infrastructure applications. The fiber sensor was made by removing portions of the poly (-methyl methacrylate) (PMMA) cladding of a plastic clad silica (PCS) optical fiber. The cladding was subsequently replaced with a thin film of PMMA doped with a pH sensitive dye (Methyl Red, Thymolphtalein, Thymol Blue). The change in the pH of the analyte is detected by sending light through the fiber while measuring the absorption spectrum of the embedded sensor molecule.",
