1. Structure Composition
The fiber optic gyro core sensor is the core component of the fiber optic gyroscope, responsible for measuring the angular velocity based on the Sagnac effect; the signal processing and control module modulates, demodulates, amplifies and digitizes the optical signals and outputs high-precision angular velocity data.
