Abstract

It is important to study the frequency noise of the laser characteristics in a resonator fiber optic gyro. A measurement of the power spectral density of optic frequency noise is introduced into a resonator fiber optic gyro. An optic optimum criterion for the frequency stabilization loop of the resonator fiber optic gyro is proposed, especially for the reduction of the locking residual error and the widening of the gyro bandwidth.
