Abstract
A test program has been conducted with a view to defining methods for reducing the drift of optical passive ring-resonator gyros (OPRG). Attention is given to such noise sources and noise-reduction techniques as Rayleigh backscattering, polarization fluctuation, and fiber-resonator optical Kerr effect. A novel, partial digital feedback scheme is defined for preventing the OPRG from lapsing into large drift, due to thermal expansion of the resonator.Keywords
