Digital Closed Loop Three Axis Integrated Fiber Optic Gyro for UGV Navigation

Product Description

TG-40M is an inertial angular rate sensor based on the optical Sagnac effect, which is used to measure the angular velocity of the carrier along the sensitive axis of the product. An angular velocity sensing unit of the product is an optical fiber ring, a digital closed-loop detection circuit is adopted to extract the optical path difference of clockwise and counterclockwise propagation light caused by external physical angular velocity and sensed by the optical fiber ring, and meanwhile, a voltage signal converted from an optical path difference signal is subjected to closed-loop feedback and control, so that the modulation and demodulation of the signal are realized, and the purpose of high-precision angular velocity signal detection is achieved.It is composed of optical angular velocity sensing unit and signal detection unit, providing gyro angular increment information and internal temperature information.They are mainly suitable for applications such as medium and high precision inertial navigation system, positioning and orientation system, servo stabilization system, etc.
