Fiber optic gyroscope uses optical methods to achieve angle measurement, so it can be started instantly without preheating time. This makes fiber optic gyroscopes perform well in application scenarios that require fast response. Fiber optic gyroscope has a wide dynamic range and can adapt to measurement requirements at different speeds and accelerations. The internal structure of fiber optic gyroscope is relatively stable and not easily affected by external vibrations. This enables fiber optic gyroscopes to function properly in rugged environments or when subjected to impacts. Some high-end fiber optic gyroscopes also adopt special anti vibration designs, further improving their anti vibration capabilities.

Fiber optic gyroscope has no rotating or friction components, therefore it has high stability and reliability. This all solid state structure reduces errors caused by factors such as mechanical wear and vibration. Fiber optic gyroscope can maintain good stability under long-term operation, which is particularly important for application scenarios that require long-term navigation and positioning.

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, as the core component of inertial navigation system, can provide high-precision three-dimensional angular velocity, position and attitude information in the aerospace field, realizing functions such as tracking and measurement of rocket launch, spacecraft stabilization, attitude measurement and control. In the field of navigation, fiber optic gyroscopes have become an important component of ship navigation equipment, providing high-precision heading information and achieving functions such as automatic north finding and pointing, attitude control, etc.
