Integration, high-precision, and low-cost optical gyroscope embodies the developing tendency of gyroscope, in which fast-light enhanced resonant optical gyroscope shows great potential. The development of the fast-light enhanced resonant optical gyroscope is overviewed through analyzing fast-light arising mechanism and considering experimental reports of dielectric dispersion and structural dispersion. By comparing the relative advantages and disadvantages in fast light generation mechanism, it is more suitable to integrate optical gyroscope system through implementing structural dispersion．Moreover, a novel structure of integrated fast-light enhanced resonant gyroscope is proposed, which may have great potential applications in low-cost civilian areas. Finally, the prospect for the development of fast-light enhanced resonant optical gyroscope in inertial navigation system is discussed.
