title: Investigation of the fundamental behavior of long-period grating sensors.
abstract: A new class of fiber optic sensor, long period gratings (LPG) optical sensors, has been investigated. The characteristics of the bare fiber LPG were studied. The LPG response to different refractive index standards, mixtures of methanol and ethanol were observed. The temperature dependence of LPG sensors was determined. A commercial LPG sensor for copper determination was evaluated.
