Fibre Bragg Grating based Attitude Sensor

Open Access Open Access

Abstract

We present a system of three Fibre Bragg Grating (FBG) curvature sensors configured as a multi-axis attitude sensor. The FBG response on each sensor provides information about its deflection due to gravity acting on a sensing mass. The three sensor system can be processed to give 3-D attitude information with an accuracy of ±2° demonstrated. The fabrication, calibration and performance of the sensors is discussed.
