Fiber optic gyroscopes are a type of device that uses changes in optical path length to measure angular velocity. They are widely used in navigation, seismic exploration, offshore oil extraction, and other fields. By using optical fiber as a sensitive element, fiber optic gyroscopes have the advantages of high precision, resistance to vibration interference, and small size, so they are widely used in many industries.
Compared to other types of gyroscopes, fiber optic gyroscopes have the following advantages:
High precision: angular velocity measurement accuracy up to 0.01°/h can be achieved;
Anti-vibration interference: The internal structure is simple and is not greatly affected by external vibrations, so it can work normally in rugged environments;
Small size: Compared with traditional mechanical gyroscopes, it is small and can be integrated into other devices.
3. Limitations of fiber optic gyroscopes
The limitations of fiber optic gyroscopes are mainly manifested in the following aspects:
The temperature has a great influence: fiber optic gyroscopes need to control temperature to ensure accuracy and reliability, otherwise temperature changes may affect the operation of the equipment;
Limited service life: components such as light sources in fiber optic gyroscopes have a certain lifespan and are prone to failure under high-intensity use, requiring regular replacement and maintenance;
High price: Compared with other types of gyroscopes, the price of fiber optic gyroscopes is still relatively high.
