Product Introduction
Introduction
LKF-F3G120 three-axis fiber optic gyroscope is an inertial angular rate sensor based on the optical Sagnac effect, designed to measure the angular velocity of the carrier along the product's sensitive axis. The angular velocity sensing unit of this product is an optical fiber ring, which employs a digital closed-loop detection circuit to extract the path difference of light propagating clockwise and counterclockwise caused by external physical angular velocity. Simultaneously, the path difference signal is converted into a voltage signal for closed-loop feedback and control, achieving signal modulation and demodulation to realize high-precision angular velocity signal detection.
