1. Product Overview
The 3-axis integrated Fiber Optic Gyroscope (FOG, Fiber Optic Gyroscope) is a high precision angular velocity sensor based on the principle of optical interference. It detects angular velocity by measuring the Sagnac effect generated when light propagates along the fiber optic ring and outputs precise attitude information. Compared to traditional mechanical gyroscopes, the FOG has the advantages of being frictionless, long-life, high-precision and shock-resistant, making it a core component in modern inertial navigation and attitude measurement systems.
The integrated three-axis design means that the gyroscope can measure the angular velocity in X, Y, and Z directions simultaneously, simplifying system integration and improving attitude measurement accuracy, which is widely used in aerospace, navigation, robotics, precision measurement, and other fields.

2. Structure Composition
The fiber optic gyro core sensor is the core component of the fiber optic gyroscope, responsible for measuring the angular velocity based on the Sagnac effect; the signal processing and control module modulates, demodulates, amplifies and digitizes the optical signals and outputs high-precision angular velocity data.
