Introduction of FOG Gyroscope
What is Fiber Optic Gyroscope ?
A Fiber Optic Gyroscope (FOG) is a highly precise and reliable device used to measure angular velocity, playing a crucial role in navigation and stabilization systems across various high-stakes applications. Unlike traditional gyroscopes, a FOG uses the principles of light transmission within optical fibers to detect rotational changes, ensuring superior accuracy and stability.
Fiber optic gyroscopes are renowned for their ability to deliver consistent, high-precision measurements, even in the most challenging conditions, making them a key component in advanced navigation and control systems.
