This fiber-optic gyroscope is a high-precision inertial angular rate sensor based on the Sagnac effect, designed to measure the rotational angular velocity of a carrier along the sensitive axis. It adopts a digital closed-loop detection circuit to capture the optical path difference of counter-propagating light inside the fiber coil induced by external rotational motion. The system converts the optical path difference into a voltage signal, and completes signal modulation and demodulation. With closed-loop feedback and control technology, it realizes stable, real-time and high-precision angular velocity signal detection.

Function

The product is composed of an optical angular velocity sensitive unit and a signal detection unit. It can stably output high-precision angle increment data and real-time internal temperature information for inertial sensing and system compensation.
