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. Main Product Features
A. High precision: Compared with MEMS gyroscope, FOG has lower offset drift and higher angular velocity resolution, which is suitable for high-precision navigation systems.
B. Three-axis integration: No need to combine multiple gyros, reducing volume and weight, improving system integration and reliability.
C. No mechanical moving parts: Compared to mechanical gyroscopes, FOG is frictionless and wear-free, resulting in longer life and higher reliability.
D. Resistant to vibration and shock: Suitable for highly dynamic environments such as drones, missiles, and flying machines.
Ready-to-use, no warm-up required: Compared to laser gyroscopes (RLG), FOG has a short start-up time and fast response.
E. Low-power design: Optimized energy consumption for battery-powered systems such as UAVs and portable navigation devices.
