Abstract

In this paper, the results of analyzing the frequency lock-in breaking characteristics of a ring laser gyroscope with random dithering through numerical experiments are presented. By observing the variant features in the frequency lock-in characteristics according to the dithering amplitude noise, it was possible to analyze the minimum noise condition that causes the frequency lock-in to be broken. It was confirmed that the result is closely related to the relative difference between the dynamic frequency lock-in corresponding to the average dithering amplitude and the frequency determined by the Sagnac effect corresponding to an input rotational angular velocity.

본 논문에서는 랜덤 디더링을 이용한 링레이저 자이로 주파수 잠김 깨짐 특성을 수치적 실험을 통해 분석한 결과를 나타내었다. 디더링 진폭잡음 크기에 따른 링레이저 자이로 주파수 잠김 특성 변화 관찰을 통해 주파수 잠김 깨짐을 유발하는 최소 진폭 잡음 크기를 분석할 수 있었다. 해당 결과는 평균 디더링 진폭에 상응하는 동적 주파수 잠김 크기 및 회전 각속도 입력에 대응하여 사냑 효과에 의해 발생하는 주파수 사이의 상대적인 차이와 밀접한 관련이 있음을 확인하였다.
