Passive fiber resonator gyro
Abstract
After presenting the design principles of the passive fiber resonator gyroscope, which possesses the good scale-factor stability and repeatability of its active, ring-laser gyro counterpart, attention is given to the state of the art in fiber-optic component fabrication, with a view to achieving the requirements of low-loss fiber resonators. Also important is the rugged narrow-band semiconductor-laser light source that had to be modified for application in a system of this kind. Such error terms as polarization cross coupling and fiber backscattering are discussed, and methods are presented with which system output can be improved.
