Which outcome diminishes a fiber optic gyroscope's precision?

💡 Explanation

Gyroscope precision decreases because loss of light source coherence reduces the interference fringe contrast, measured by the Sagnac effect. This undermines accuracy because fringe visibility must exceed a performance threshold, rather than bandwidth or polarization effects alone.
