Abstract: Utilize the principle of fiber optic gyroscope measure rotational velocity to measure rotation shaft torque. Sum up the principle, development and utilization of torque measurement. Measure the relatively rotation speed of twain section using twain fiber optic gyroscope. By integral the relatively rotation speed, gain the relatively rotation angle, further realize torque measurement. realize dynamics observation of main drive for large mechanism equipment, which can provide the foundation of the equipment automatization and intelligentization.

Key words: Optics Sagnac effect  Fiber optic gyroscope  Measure torque  Dynamics observation
