2025 Single Axis Fiber Optic Gyroscope Inertial Sensor for Inertial Navigation System
The MFOG-24 micro-nano fiber optic gyroscope (hereinafter referred to as the product) is a high-precision angular rate sensor that integrates optical, mechanical, and electronic technologies. It is based on the Sagnac effect, utilizing interference between two beams of light propagating in opposite directions within a fiber loop to detect angular velocity. By detecting, processing, and feeding back the phase difference generated during this process, the product achieves precise measurement of angular motion.
This gyroscope features a compact design and integrates various micro-nano fiber devices to ensure high sensitivity and stability. Its internal structure is optimized for performance and reliability, featuring no moving or wearing parts, which enables quick start-up, low maintenance, and excellent durability. Due to its small size, lightweight, and robust construction, it is ideally suited for applications requiring precise attitude control and motion sensing, such as in unmanned systems, navigation platforms, and aerospace vehicles.
The product is mainly composed of the following components:
A) an optical path assembly;
B) Detection and control signal circuit board;
C) Optical fiber ring skeleton, shell and other structural parts
