Fiber optic gyroscope and angular velocity sensor with dynamic range ±900°/s, random walk ≤0.01°/h^1/2, and bias drift ≤0.3°/h for inertial systems
This device serves as an inertial angle rate sensor utilizing the optical Sagnac effect to measure the rotational angular velocity of the carrier along its sensitive axis. Employing a digital closed-loop detection circuit, it extracts the optical path difference caused by external physical angular speed in a clockwise direction. Through modulation and demodulation of the optical path signal voltage, closed-loop feedback and control are implemented, enabling real-time detection of angular velocity signals.
Function: This product consists of two parts: optical angular velocity sensitive unit and signal detection, providing uniaxial angle increment information and internal temperature information.
Application scope: The products are mainly suitable for photoelectric crane / crane / flying platform / inertial navigation / inertial measurement system / optical / photographic instrument / platform stabilization device / inertial measurement instrument and other applications.
