500deg/S Range Gyro Sensor One Axis Gyro Rate Sensor Low Cost Small Size FOG
Introduction
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, 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 rate, which is sensed by the optical fiber ring, and meanwhile, a voltage signal converted from an optical path difference signal is subjected to closed-loop feedback and control, so that the modulation and demodulation of the signal are realized, and the purpose of angular rate signal detection is achieved.
This product is composed of an optical angular velocity sensing unit and a signal detection unit, providing single-axis angular increment information and internal temperature information.
The products are mainly suitable for applications such as medium-precision inertial navigation systems, positioning and orientation systems, and servo stabilization systems.
