Abstract

An absolute displacement-sensing system based on channeled spectrum processing capable of simultaneous interrogation of fiber Bragg gratings and fiber-optic interferometric sensors is presented in which the role of the optical spectrometer is performed by a scanning Fabry–Perot filter. We demonstrate a resolution of ± 50 nm with an estimated dynamic range of 1 part in 105.
