Abstract

This paper introduces a novel fiber Bragg grating (FBG) sensor for hull roll and pitch motion measurement. The sensor is mainly composed of three parts: differential hinge structure, fiber grating and mass block. When the hull produces a dip angle affected by external forces, the fiber gratings fixed on the left and right sides are deformated due to the tensile and the pressure force. The relationship between the deformation of the fiber gating and its wavelength is subjected to the proportional function. By using compensation algorithm of the demodulator, we can get the fiber wavelength and the inclination angle of the ship.
