Backscattering noise is a key factor to restrict the performance of resonant fiber optic gyroscopes(RFOG). In order to improve the accuracy of RFOG, this paper proposes a scheme with heterodyne optical phase-locked loop(HOPLL) technique based on acou

In the conventional hull deformation measurement method, the external measurement noise is considered constant. However, due to the complex sea conditions and the high-frequency chatter caused by the waves, the measurement noise is colored noise. The

In recent years, the performance of an interferometric fiber optic gyroscope (IFOG) has been increased a lot and widely used for dynamic angle measurement. In this paper, we present an investigation on measurement uncertainty of the IFOG and propose
