Product Details

ER-FOG910 Fiber Optic Gyro use 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.

Note1: refer to the time from the start-up to meet the performance indicators

Note2: the bias stability and the random walk coefficients are measured by the Alan

variance analysis under the laboratory steady temperature conditions.

Note3: use GJB-2426A method for statistics, the correlation time is 10s.
