This product is an inertial angular rate sensor based on the optical Sagnac effect, which is used to measure the angular rate of the carrier along the sensitive axis of the product. An angular rate 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 rate 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 rate signal detection is achieved.

This product consists of an optical angular velocity sensing unit and a signal detection unit, and provides information of three-axis angular increment and internal temperature.

The products are mainly suitable for high-precision inertial navigation systems, positioning and orientation systems and other applications.
