Abstract

Frequency lock-in is the most principal phenomenological feature to be characterized and eliminated for the development of high precision ring laser gyroscope (RLG). As an effective method to solve the lock-in induced problem, sinusoidal dithering by mechanical manner has been proposed and has widely used successfully to date. However, in real applications, pure-sinusoidal dithering is nearly impossible, so additional nonlinear factors should be considered for modeling of dithered RLG. In this work, output variations of RLG in the presence of non-ideal sinusoidal dithering are investigated by performing numerical experiments.
