The product is an inertial angular velocity sensor based on the Sagnac effect for measuring the rotational angular velocity of the carrier along the sensitive axis. The digital closed-loop detection circuit is used to extract the optical path difference of the counterclockwise propagating light caused by the external physical angular speed of the optical fiber coil. At the same time, the voltage signal of the optical path difference signal is converted to modulation and demodulate the signal, and the closed-loop feedback and control are realized to achieve the purpose of real-time angular velocity signal detection.
