HS-90 Fiber Gyroscope

HS-90 FOG is an inertial angular velocity sensor based on the optical Sagnac effect, used to measure the angular velocity of a carrier along the sensitive axis of the product. The angular velocity sensing unit of this product is a fiber optic ring, which uses a digital closed-loop detection circuit to extract the optical path difference of clockwise and counterclockwise propagating light sensitive to the external physical angular velocity of the fiber optic ring. At the same time, the optical path difference signal is converted into a voltage signal for closed-loop feedback and control, achieving signal modulation and demodulation, and achieving high-precision angular velocity signal detection.

This fiber gyroscope consists of an optical angular velocity sensing unit and a signal detection unit, providing single axis angular increment information and internal temperature information
