Dynamic lock-in compensation for mechanically dithered ring laser gyros

Year: 2012

Type: article

Abstract: 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.
