fiber optic gyroscope
A fiber optic gyroscope is a device that detects rotation or changes in orientation using the properties of light traveling through thin, flexible fibers of glass or plastic. When the device rotates, light beams traveling in opposite directions through the fiber experience slight differences in phase, which can be measured to determine the rate of rotation. This technology relies on the physics of light interference and does not involve moving parts, making it highly sensitive and reliable for navigation, aircraft stability, and other applications where precise rotation detection is essential.
