摘要

In ring laser gyros (RLGs),dynamic lock-in,which results from information loss in the lock-in region,occurs when a constant sine bias is introduced.However,sampling some signals in the lock-in region for a particular duration allows the retrieval of lost information.It is demonstrated how dynamic lock-in and the flat region in the input-output curve near the zero angle rate can be eliminated after compensation.
