Fiber Optic Gyroscope: Steady Navigation Technology Leading the Future
As an important inertial navigation technology, fiber optic gyroscope has shown great potential in the fields of aerospace, ocean exploration and high-precision positioning. Its high precision, long life and good environmental adaptability make the fiber optic gyroscope one of the key technologies in the future navigation field. This article explores the promise of fiber optic gyroscopes and demonstrates the dramatic changes it may bring in future developments.
The principle and characteristics of fiber optic gyroscope：
Fiber optic gyroscope is an inertial navigation instrument based on the principle of optical interference, which uses the characteristics of light propagating in optical fibers for measurement. Its core components include fiber optic loops and lasers, and the angular velocity of rotation is determined by measuring the interference of light in the fiber. Compared with traditional mechanical gyroscopes, fiber optic gyroscopes have the following notable features:
High precision: The measurement accuracy of the fiber optic gyroscope has reached the sub-angle level, which can achieve very accurate attitude and angular velocity measurement, providing extremely high accuracy guarantee for navigation and positioning.
Long life: Since the fiber optic gyro has no rotating parts, there is no wear and friction, so it has a long life and can work for a long time in harsh environments.
Strong environmental adaptability: The fiber optic gyroscope has strong adaptability to environmental factors such as temperature, humidity and vibration, and can work stably in various complex environments.
Application prospect of fiber optic gyroscope in aerospace field：
The aerospace field has extremely high requirements on navigation accuracy and reliability, and the fiber optic gyroscope is an ideal choice to meet these requirements. It can be applied to aircraft, missiles, satellites and other vehicles to provide accurate attitude measurement and navigation information to ensure the stability and safety of the aircraft. Compared with traditional mechanical gyroscopes, fiber optic gyroscopes have higher shock resistance and longer service life, and can adapt to extreme environments.
