Chinese Factory Supply Single Axis Gyroscope Sensor to Replace VG1703 Fiber Optic Gyroscope
Product Overview
The MFOG-40 Micro-Nano Fiber Optic Gyroscope is an advanced angular rate sensor that seamlessly integrates optical, mechanical, and electronic technologies. Based on the Sagnac effect, it utilizes cutting-edge micro-nano fiber devices to achieve high-precision measurement. The gyroscope detects angular velocity by monitoring the phase difference generated between two light beams propagating in opposite directions, processing this information through sophisticated electronics, and providing precise feedback for control or measurement purposes.
This product is designed with simplicity and reliability in mind. It features a compact and lightweight structure, with no moving parts or components subject to wear, ensuring long-term stability and durability. Its fast start-up capability, combined with its small size and low weight, makes it highly suitable for applications in attitude control, navigation, and motion measurement of various carriers, including aerial, marine, and ground platforms.
