Three-Axis Fiber Optic Gyroscope Inertial Angular Rate Sensor Optical Sagnac Effect Gyro Sensor
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. The angular rate 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 anticlockwise propagating light caused by the external physical angular rate, 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.
