This product is an inertial angular velocity sensor based on the optical Sagnac effect, used to measure the rotational angular velocity of a carrier along the sensitive axis direction. The digital closed-loop detection circuit is used to extract the optical path difference of clockwise and counterclockwise propagating light sensitive to external physical angular velocity in the fiber ring. At the same time, the optical path difference signal is converted into a voltage signal for signal modulation and demodulation, and closed-loop feedback and control are implemented to achieve real-time angular velocity signal detection.
Function: This product consists of an optical angular velocity sensing unit and a signal detection unit, providing single axis angular increment information and internal temperature information.
Application scope: The product is mainly suitable for applications such as optoelectronic lifting chambers, aerial platforms, strapdown inertial navigation systems, inertial measurement systems, optical/photographic instruments, platform stabilization devices, inertial measurement instruments, etc.
