Fiber optic gyroscopes have low cost and easy maintenance. They are replacing mechanical gyroscopes on many existing systems, thereby greatly improving system performance, reducing and maintaining system costs. Now, fiber optic gyro has fully utilized its advantages such as light weight, small size, low cost, high accuracy and high reliability, and is gradually replacing other types of gyro.
In the future, the research trends of fiber optic gyros are: (1) using three-axis measurement instead of single axis, research and development of multi-functional integrated optical chips, polarization maintaining technology, etc., to increase the miniaturization and low cost of fiber-optic gyros; 3. The application of low-precision fiber optic gyroscope, especially civil inertial navigation technology; (3) Strengthen the technology and application research of precision fiber-optic gyroscope, and develop new fiber-optic gyroscope B-FOG and FRLG.
