“…The attitude measurement is important to the attitude control for a system and has some serious applications in aviation and space, warship weapon, vehicle, and machining automation [1,2]. The accurate measurement of attitude information is the basis of realizing precise guidance, navigation and balance stability of the carrier [3]. Attitude information refers to the orientation, pitch angle and roll angle relative of the carrier to some coordinate system, which shows the status of the carrier and provides the basis for accurately determining if the carrier is in a controllable state and meets the expected design requirements [4].…”

We proposed a new approach to attitude measurement by an evanescent field-based optical fiber sensing device and demonstrated a liquid pendulum. The device consisted of three fiber-optic evanescent-filed sensors which were fabricated by tapered single mode fibers and immersed in liquid. Three fiber Bragg gratings were used to measure the changes in evanescent field. And their reflection peaks were monitored in real time as measurement signals. Because every set of reflection responses corresponded to a unique attitude, the attitude of the device could be measured by the three fiber-optic evanescent-filed sensors. After theoretical analysis, computerized simulation and experimental verification, regular responses were obtained using this device for attitude measurement. The measurement ranges of dihedral angle and direction angle were 0°–50° and 0°–360°. The device is based on cost-effective power-referenced scheme. It can be used in electromagnetic or nuclear radiation environment.
