Abstract
Interferometric noise in fiber-optic grating sensors is investigated. Interference between a signal wave and reflected waves causes signal fluctuation in the output that limits the wavelength detection accuracy of the sensing system. The measurement error limited by interferometric noise is calculated for both reflective-type and transmission-type sensors.
