Fiber optic gyro

Fiber-optical gyroFiber-optical gyro is used the principle of interference of Sagnac, make the laser as light source, light path of loop type is constructed by fiber, and inspectphase differences oftwo routeslaser 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.Fiber-optical gyro, itscharacteristi
