Product Description
Single Axis Optical Gyro Low Bias Close Loop Gyroscope 200Hz Output Rate Inertial Gyro Sensor
The F70 is the interferometric digital close-loop single-axis fiber optic gyro. It is the perfect substitution for traditional mechanical gyro, featuring of high bandwidth, short activation time, shock resistance, vibration resistance and affordable cost. The F70 FOG adopt the embedded digital signal processor. The integrated adaptive filter reduces the bias stability and angle random walk by 50%-70%,technology which not only reduces the impact of the temperature but also significantly improves the bias stability, angle random walk, scale factor linearity and robustness. The exceptional bias stability, angle random walk and resistance to shock make it ideal for various navigation and industrial applications. F70 is a angular speed sensor integrated with light, mechanism and eletricity. it is based on Sagnac ef fect and close loop control test technology. it tests, processes and feedbacks by the phase difference p roduced by two oppsite transmission light, realising the whole close loop process. the item is mainly composed by optical path units, circuit units and structural unit. it has simpler structur e, no moving parts, no wearing parts, quicker start, smaller volume and ligher comparing with electrom echanical gyro. It could be widely used in missile guidance and control, positioning and aiming system of tank and fighting vehicle, ship's photoelectrical tracking syste
Composition
a) optical path unit: including erbium-doped light source, fiber ring, integrated optical phase modulator, fiber coupler, photodetector;
b) circuit unit: light source driving circuit, detection and control signal circuit board;
c) Gyro structural parts.
