FOG120 Low cost Open loop Fiber optic Gyroscope

FOG120 is an outstanding performance open loop fiber optic gyroscope series developed by FOGPhotonics,inc.We use one piece single mode fiber without fusion point to develop this low cost open loop fiber optic gyroscope.The FOG120 series delivers superior stability and reliable performance at affordable cost and smaller size than other comparable gyros in general, and FOG in particular.The performance of gyros and systems can be optimized for specific requirements and applications on an individual basis. FOGs can be supplied as a stand alone single axis, or as a dual/ triad with common electronics. All FOGs are available with a flexible interface configuration.
