This product is a kind of inertial angular rate sensor based on optical Sagnac effect, which is used to measure the rotational angular velocity of the carrier along the direction of the sensitive axis. The digital closed-loop detection circuit is used to extract the optical range difference of the clockwise and counterclockwise propagation of light caused by the external physical angular velocity of the fiber optic ring sensitive to the optical range difference signal converted into a voltage signal for the modulation and demodulation of the signal, and to achieve closed-loop feedback and control, 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 instrument/platform stabilization device/inertial measurement instrument.
