Inside a typical optical gyroscope, a spooled-up optical fiber carries pulses of laser light. However, the optical gyro operates by using light passing through a coil of optical fiber. In this way, an optical gyro functions similarly to a mechanical gyro. ![]() These machines and other platforms depend on fiber optic gyroscopes to operate safely.Ī fiber optic gyroscope detects changes in position or direction using the Sagnac effect. This research breakthrough could lead to more accurate fiber optic gyros compared to mechanical units.Īdvanced fiber optic navigation technology is critical for aircraft, missiles, unmanned aerial vehicles and ground vehicles. Five hundred times smaller than a regular gyroscope, this new gyro can fit on a grain of rice. ![]() ![]() ![]() Engineers at the California Institute of Technology have created the world’s smallest fiber optic gyroscope.
