Highly Accurate 3-Axis FOG with Wide Measuring Range and Random Walk Coefficient of ≤0.0003°/√h

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. Product Core Technology
The 3-axis integrated fiber optic gyroscope integrates a number of advanced technologies to ensure high accuracy, low drift and stability:
A. Fiber optic ring technology: high quality fiber optic manufacturing, optimized fiber optic winding process to reduce temperature drift and fiber optic non-uniformity effects.
B. Closed-loop control: Digital Signal Processing (DSP) and closed-loop modulation technology to improve gyro output stability and dynamic range.
C. High-precision signal processing: low-noise photodetector and signal filtering algorithms to improve signal quality and reduce the impact of noise.
D. Temperature Compensation Algorithm: Integrated temperature sensor and temperature compensation algorithm to ensure that it can still maintain high precision measurement in different environments.
E. High Reliability Structure Design: Adopting anti-shock and anti-vibration design to ensure stable operation even in harsh environments.
