3 Axis Close-Loop Fiber Optic Gyroscope
This product is a three-axis fiber optic gyro, The fiber ring and circuit acquisition board are designed separately, which can avoid the influence of the circuit temperature changing to affect the fiber accuracy. We can provide customers with separate three-axis gyro, and we can also customize the installation to the structure according to customer requirements to complete the three-axis calibration.
