Design of Frequency Stability and Lock Stability Control System for Ring Laser Gyroscope

摘要

It is of great importance to improve performance of ring laser gyroscope by ameliorating lock characteristic. After careful research on lock control principle, lock minimization and lock stabilization of back-scattering are presented. Frequency stabilization and lock stabilization control system is designed, and is demonstrated by a ring laser gyroscope frequency stability and lock stabilization parameter test system which is developed on basis of the technique. The result shows that the technique fully satisfies design requirements of the ring laser gyroscope.
