The influence of fiber fusion parameters on the performance and reliability of FOG

As a new generation of optical gyroscope, fiber optic gyroscope has the characteristics of high precision, zero start, all solid state, high theoretical reliability, and has been widely used in many fields, such as sea, land, air and so on. In the assembly process of FOG, the fiber fusion technology is one of the key technologies of FOG. Its process method and parameters have a decisive influence on the performance and reliability of FOG. In this paper, the flow chart based on FOG fusion technology is established firstly, and the influence mechanism of FOG fusion technology on its performance and reliability is analyzed. Then, the relevant tests are designed and verified. Finally, the performance and reliability of FOG are improved by optimizing the technological parameters of fiber fusion and carrying out strict technological management system.
