1 February 1992 Laser intensity noise in a fiber optic gyroscope system due to signal feedback
Author Affiliations +
A theoretical and experimental treatment is presented for the feedback-dependent intensity-noise characteristics of a laser diode used in a FOG. The feedback induces an additional, time-varying noise signal in the laser output which has the same waveform as the Sagnac signal, and is amplified by as much as 13 dB. The effect of this intensity noise in the output of a 2D frequency-division multiplexed gyro is to introduce two additional terms.
