This product 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.
The angular velocity sensing unit of the product is an optical
fiber ring, and a digital closed-loop detection circuit is adopted
to extract the optical path difference of clockwise and
counterclockwise propagation light caused by the external physical
angular velocity, which is sensed by the optical fiber ring,At the
same time, the voltage signal converted from the optical path
difference signal is used for closed-loop feedback and control to
realize the modulation and demodulation of the signal and achieve
the purpose of high-precision angular velocity signal detection.
