Product Description

Inertial Angular Rate Sensor Optical Sagnac Effect Gyroscope Closed-Loop 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. An angular rate sensing unit of the product is an optical fiber ring, a digital closed-loop detection circuit is used for extracting the optical path difference of clockwise and counterclockwise propagation light caused by external physical angular rate and sensed by the optical fiber ring, and meanwhile, the optical path difference signal is converted into a voltage signal for closed-loop feedback and control, so that the modulation and demodulation of the signal are realized, and the purpose of high-precision angular rate signal detection is achieved.
