FOGs are developed for industrial applications such as car navigation or location systems, self-guided robots, bore-hole route survey systems, geodesic compasses, etc. The FOGs are based on an open loop and minimum reciprocal configuration with all polarization maintaining (PM) fiber components. Because the fiber optic components are almost ready for mass production, FOGs provide an attractive economical aspect.
