FOG-B2 High performance low cost fiber optic gyro. The FOG-B2 is the interferometric digital close-loop single-axis fiber optic gyro, with the features of high bandwidth, short activation time, shock resistance, vibration resistance and affordable cost. The FOG-B2 utilizes the patented IntelliProcess 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 industrial applications. Technical Specifications: Performance Specifications: Maximum Input Rate((°/s) : ±4 Scale Factor (°/s/bit) :0.000125[1] Scale Factor Linearity(% rms) :

Fiber Optic Gyro

Fiber-optical gyro used the principle of interference of Sagnac, make the laser as light source, light path of loop type is constructed by fiber, and inspect phase differences of two routes laser beam, the phase differences was caused by two beam (two beam from the pro and con hour hand was transmitted along optical fiber) rotated along with fiber loop, then will calculate the rate of angular speed of the optical gyroscope.
