Abstract
A fiber optic gyroscope inputs laser light into opposing ends of a fiber optic coil and detects light at the same ends of the optical fiber. A pulse-per-second signal is generated by determining the phase difference between the two opposing laser light signals, and generating electrical pulses based on this detected phase difference. The fiber optic gyroscope may become a source of one or more PPS signals used by a vehicle.
