Single Axis Fiber Optic Gyro ±300°/s Range 3°/h Stability
The MFOG-091D micro-nano fiber optic gyroscope is an advanced angular rate sensor that integrates optics, mechanics, and electronics. Based on the Sagnac effect, it utilizes micro-nano fiber devices to detect, process, and feedback the phase difference generated by counter-propagating light beams.
- Simple structure with no moving or wear parts
- Fast start-up time and compact design
- Lightweight construction for versatile applications
- Ideal for attitude control and carrier measurement systems
- Optical path assembly
- Detection and control signal circuit board
- Fiber coil skeleton and structural components
Dimensions: φ24mm × 51.6mm
