Optical gyroscope

An optical gyroscope is a device that detects rotations or changes in orientation using light rather than spinning parts like traditional gyroscopes. It works on principles like the Sagnac effect, where two beams of light travel in opposite directions around a loop. When the device rotates, the travel times of these beams change slightly, creating a measurable interference pattern. This allows the gyroscope to determine how much the device has rotated without moving parts, making it highly precise and reliable. Optical gyroscopes are commonly used in navigation systems for aircraft, submarines, and spacecraft, especially where GPS signals may not be available.
