What is a Fiber Optic Gyroscope (FOG)?
A Fiber Optic Gyroscope (FOG) is a high-precision attitude control and inertial sensor that uses the properties of light to accurately measure an object’s angular velocity (rotational speed). Unlike conventional mechanical gyroscopes, it has no moving parts such as rotating flywheels, making it highly durable with exceptionally low wear and failure rates. By utilizing a long optical fiber with a high number of turns (such as polarization-maintaining fiber), it can detect extremely subtle changes in rotation with ultra-high sensitivity.
