Control Grade TDFG70S Fiber Optic Gyroscope
1 Introduction
The fiber optic gyroscope (FOG) is an angular velocity sensing device that operates on the Sagnac effect in optical systems. Leveraging advanced all-digital closed-loop control systems, it delivers real-time angular velocity measurements of moving platforms via high-speed serial interfaces with sampling rates exceeding 4 kHz. Available in single-axis, dual-axis, and three-axis configurations, this product line enables multi-axis synchronization for dynamic motion analysis. Dual and three-axis variants achieve simultaneous orthogonal-axis detection through integrated designs featuring shared optical components and electronic processing units, ensuring precise measurement coherence across all axes.
2 Application
It is suitable for stabilization and control equipment for guided weapons, tactical missiles, torpedoes, attitude control, and medium and high-end industrial equipment.
3 Characteristics
All-solid-state design with no moving parts;
Instant-on, digital output for easy connection to a computer;
Small size, light weight and flexible design;
Low noise, low power consumption, low cost;
High reliability and long life.
