Dynamic lock-in compensation for mechanically dithered ring laser gyros

Zhenfang Fan, Hui Luo, Guangfeng Lu, and Shaomin Hu

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.
