| Abstract: | Lock-in effect is an important factor in Ring Laser Gyro(RLG) error. Mechanical dithering is a widely used bias method to eliminate lock-in effect. Thus, the reliability of the dither system is crucial to RLG. A work principle and a design method of the dithering circuit is discussed in this thesis, also a work method of forced dither is developed to improve its reliability. |
