The development of fiber optic gyroscopes faces some technical difficulties, such as sensitivity loss, drift caused by noise and fiber birefringence, and unstable scaling factor caused by polarization state changes. In order to overcome these difficulties, researchers are constantly exploring new technologies and methods, such as using high birefringence fibers and optimizing fiber optic wrapping techniques. In the civilian field, fiber optic gyroscopes are mainly used for automatic navigation, positioning and orientation, vehicle control of ground vehicles, as well as attitude control of agricultural aircraft, positioning tools and rescue tools in underground engineering maintenance.

Fiber optic gyroscope is an inertial sensor based on fiber optic technology, used to measure and detect rotational speed and direction.
