| dc.description.abstract | The development of a fiber optic sensor for measurement of the differential rotation rate between
two parallell axis is reported. Different designs based on the Sagnac Interferometer are considered,
and a design for use in hull monitoring systems are recomended and demonstrated with the use of
two standard interrogation techniques for optical gyroscopes. The recomended design consists of
two fiber coils connected in series in a way such that light waves propagating in one direction in
one coil, will propagate in opposite direction in the other coil. Since the two coils are connected by
optical fiber, the sensor system are designed to measure oscillations or vibrations. The rotation rate
sensor is insensitive to rotations equal for the two coils. The application at hand is measurement
of vibration modes(e.g torsion) for use in hull monitoring systems in large sized objects such as
ships and airplanes, where the amplitude of torsion oscillations indicates the load of the object. | en_GB |
