Research on Modulation Stability and Compensation Method of Y Waveguide in Fiber Optic Gyroscope

摘要：

Based on the study of the principle of ladder wave modulation in digital closed-loop fiber optic gyroscope,the temperature characteristics of Y waveguide half-wave voltage is analyzed and verified by experiment,then the influences of modulation stability of Y waveguide on fiber optic gyroscope is investigated,and the real-time tracking of compensation method for the modulation instability of Y waveguide is researched and designed. The stability of scale factor,the output interference signal during ladder wave reset period and the zero bias stability of fiber optic gyroscope are tested by comparison experiments whether the real-time tracking of compensation method is adopted..It obtained the conclusion that the modulation stability of Y waveguide is the main reasons affect the accuracy of high-precision fiber optic gyroscope,the accuracy and stability of fiber optic gyroscope has been greatly improved by adopting real-time tracking of compensation method for Y waveguide.
