Abstract:

The compensation of Dead Band is an important problem in designing a closed loop Fiber Optic Gyroscope. The author measured Dead Band in the output signal of the closed loop FOG by the measuring method of small rotation rate and adopted a convenient method of biasing the output phase shift of closed loop FOG to compensate Dead Band. Some important problems concerning how to implement the above method have been discussed.

Key words: fiber optic gyroscpe, fiber optic sensor, electric coupling
