FOG(Merak-50S)
The Fiber Optic Gyroscope (FOG) is an angular rate sensor based on the Sagnac optical effect, employing high-performance all-digital closed-loop detection technology. It provides real-time angular velocity output exceeding 4kHz via serial interface. The product series includes single-axis, dual-axis, and three-axis configurations, with multi-axis variants utilizing shared light source and processing circuitry for synchronous orthogonal axis measurement.
Applications include guidance systems, attitude control, torpedoes, tactical missiles, and industrial stabilization equipment.
Key features:
1) Compact, lightweight modular design;
2) All-solid-state construction;
3) Instant startup with digital interface;
4) Low noise/power/cost characteristics;
5) High reliability and extended lifespan.
