Customized FOG Fiber Optic Angular Rate Sensor for Inertial Measurement Unit
The MFOG-103 micro-nano fiber optic gyroscope is a high-performance angular rate sensor that integrates optical, mechanical, and electronic technologies. Based on the Sagnac effect, it incorporates multiple micro-nano fiber optic devices and measures angular rate by detecting, processing, and feedback-controlling the phase difference generated by two counter-propagating light beams within the fiber coil.
The product features a simple and robust structure with no moving or wearing parts, offering fast start-up, compact size, light weight, and high reliability. The MFOG-103 is suitable for attitude measurement and control applications across various carrier platforms.
- Optical path assembly
- Detection and control signal circuit board
