STG-90H is an inertial angular velocity sensor based on optical Sagnac effect, which is used to measure the rotation angular velocity of the carrier along the sensitive axis. The digital closed-loop detection circuit is adopted to extract the optical path difference of the clockwise and counterclockwise propagation light caused by the external physical angular velocity, which is sensed by the three-axis sensing meter head, and simultaneously, the optical path difference signal is converted into a voltage signal to carry out the modulation and demodulation of the signal, and the closed-loop feedback and control are realized to achieve the purpose of real-time angular velocity signal detection.It consists of an optical sensing meter unit and a circuit box, and provides three-axis angular increment information and internal temperature information externally.They are mainly suitable for applications such as strapdown inertial navigation/inertial measurement system, positioning and orientation system and high-precision control platform.
