The HTG-40 three-axis integrated optical gyro is an all solid state digital closed-loop fiber optic gyroscope based on the SAGNAC principle. Composed of SLD light source, fiber coupler, photodetector, integrated optical phase modulator, fiber sensing ring, circuit and structural body.
Transforming into a miniaturized inertial measurement system design, it has the characteristics of small size, high precision, high reliability, and flexible structure. We can produce according to the customer’s design of the platform.
