Which effect occurs within a fiber optic gyroscope when optical path lengths diverge beyond the coherence length?

💡 Explanation

The Sagnac effect signal degrades because, while the optical path difference remains, the interfering beams are no longer coherent; therefore the intended interference fringes are attenuated, rather than stronger effects occuring under increased coherence.
