This product is an inertial angular rate sensor based on the optical Sagnac effect, used to measure the rotational angular velocity of the carrier along the sensitive axis direction. The digital closed-loop detection circuit is used to extract the optical range difference of clockwise and counterclockwise propagation of light caused by external physical angular velocity sensitive to the fiber optic ring, and at the same time, the optical range difference signal is converted into a voltage signal for signal modulation and demodulation, and to realize the closed-loop feedback and control, so as to achieve the purpose of real-time angular velocity signal detection.
Function: The product consists of two parts: optical angular velocity sensitive unit and signal detection, providing single-axis angular increment information and internal temperature information.
Application: The product is mainly suitable for the application of optoelectronic silo/flying air platform/Jetlink inertial guidance/inertial measurement system/optical/photographic instruments/platform stabilization devices/inertial measurement instruments, and so on.
