Amplified fiber ring resonator gyro
Amplified fiber ring resonator gyro
The sensitivity of a fiber-optic ring resonator gyro increases with increasing resonator finesse, which can be achieved by including a fiber amplifier in the ring. The spontaneous emission from a fiber amplifier introduces additional noise. The effect of this noise on the performance of an ARRG is theoretically investigated, assuming an infinity source coherence length. It is found that for a given fiber length, the uncertainty in measuring the rotation rate with an ARRG can be more than one order of magnitude lower than with a shot noise limited PRRG, and about three orders of magnitude lower than with an IFOG.

Abstract
The sensitivity of a fiber-optic ring resonator gyro increases with increasing resonator finesse, which can be achieved by including a fiber amplifier in the ring. The spontaneous emission from a fiber amplifier introduces additional noise. The effect of this noise on the performance of an ARRG is theoretically investigated, assuming an infinity source coherence length. It is found that for a given fiber length, the uncertainty in measuring the rotation rate with an ARRG can be more than one order of magnitude lower than with a shot noise limited PRRG, and about three orders of magnitude lower than with an IFOG.
