Abstract

Experiments were carried out to quantify the contribution of backscattered light and orthogonal polarization to the bias stability of a tactical-grade resonant fiber-optic gyro. The data were found to agree with theory to within 25 percent. It was found that suppressed carrier phase modulation of the light for each input was effective in reducing the backscatter bias error by shifting the modulation frequencies for the counterpropagating signals. The polarization errors could be reduced by adding fiber polarizers at the ring outputs.
