Abstract

One of the main sources of fiber optic gyro noise is the polarization error of gyro. Integrated fiber optic gyroscope can reduce gyroscope volume and cost. Many researchers at home and abroad have designed and produced integrated optical path devices of fiber optic gyroscope, but there is still a lack of an effective performance evaluation method. According to the physical model of fiber optic gyroscope and Jones matrix theory, the optical devices in small fiber optic gyroscope are studied in this paper. The physical model of discrete optical path device and the transmission model of integrated optical path device system of small interferometric fiber optic gyroscope are established. The influence of non-ideal factors of integrated devices on polarization error of gyro system is analyzed. In the design process of integrated optical path gyroscope, the research method in this paper can select the components according to the different precision requirements of gyroscope. The research method in this paper can effectively evaluate the performance of integrated optical path devices of small interferometric fiber optic gyroscopes.
