Abstract

In this paper, we set up a dynamic output model of fiber optic gyroscope and analyze the testing method of dynamic characteristics of fiber optic gyroscope. In accordance with the feature of the noise in the testing, we research the filter methods through making a comparison of advantage and disadvantage among weighted average filter, IIR digital filter and wavelet analysis in testing of dynamic characteristics. Both theoretical analysis and experimental results demonstrate that wavelet analysis has an obvious effect in testing of dynamic characteristics of fiber optic gyroscope.
