Low Price Fiber Optic Gyroscope Short Activation Time for Inertial Measurement Unit

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.

Performance characteristics

High precision: Fiber optic gyroscopes have high measurement accuracy and can meet the needs of high-precision navigation and positioning.

High stability: Due to the solid-state structure of fiber optic gyroscopes, there are no rotating or friction components, making them highly stable and reliable.

Fast response: Fiber optic gyroscopes can quickly respond to changes in rotational speed, achieving fast navigation and positioning.

Anti vibration: Fiber optic gyroscopes have strong anti vibration capabilities and can work normally in harsh environments.

Fiber optic gyroscope is mainly composed of fiber optic ring, light source, photodetector, and signal processing system. Its working principle is based on the Sagnac effect, which means that when a beam of light travels in a circular channel, if the circular channel itself has a rotational speed, the time required for the light to travel along the direction of rotation of the channel is longer than the time required to travel along the opposite direction of rotation of the channel. By measuring this time or phase difference, the rotational angular velocity of the gyroscope can be calculated.

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