摘要：
This study proposes a combination of fast and slow dithering in a ring laser gyroscope (RLG) and analyzes the related characteristics through numerical experiments. The results of this study are significant compared to the existing methods that use sinusoidal dithering with a single frequency component. The results show that the proposed method can contribute to developing new alternatives for improving RLG performance when high static lock-in frequencies are considered.
