Product Introduction:
This product is an inertial angle rate sensor based on the optical 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 clockwise light caused by the external physical angular speed, and the voltage signal of the optical path signal is modulated and demodulation, and the closed loop feedback and control are realized to achieve the purpose of real-time angular velocity signal detection.
Function: This product is composed of optical angular velocity sensitive unit and signal detection, providing triaxial Angle increment information and internal temperature information.
