Recent research on future evolution of fiber optic gyros is discussed. Research factors to improve the functions of interferometer fiber optic gyros in regard to light-source characteristics, temperature change induced drift, and cost reduction are reviewed, and resonator fiber optic gyros and Brillouin fiber optic gyros are evaluated as next generation configurations.
Key words : interferometer FOG, resonator FOG, Brillouin FOG
