3-axis FOG with low-noise
,high-precision three axis gyroscope
,FOG gyroscope for INS systems
This product is a high-precision inertial angular velocity sensor based on the Sagnac effect, designed to measure the rotational angular velocity of a carrier along its sensitive axis. Equipped with a digital closed-loop detection circuit, the system captures the optical path difference of counter-propagating light in the fiber coil generated by external rotational motion. The collected optical path difference signal is converted into a voltage signal for professional modulation and demodulation. Combined with closed-loop feedback and control technology, the sensor achieves accurate and real-time angular velocity detection.
Function
The gyroscope consists of an optical angular velocity sensitive unit and a signal detection unit. It outputs high-precision angle increment data and real-time internal temperature information for system measurement, data compensation and state monitoring.
Application Areas
This sensor is widely applied in photoelectric cranes, aerial flying platforms, transportation equipment, inertial navigation systems, inertial measurement systems, optical and photographic instruments, platform stabilization equipment and other high-precision inertial measurement scenarios.
