Research on the Modulation Phase Distortion Error Character of Y Wave-Guide in Fiber Optic Gyroscope


Y wave-guide is an essential component in the close-loop interference fiber optic gyroscope (IFOG) system. The application of Y wave-guide in IFOG enables FOG to have high scale factor linearity and has significantly improved scale factor stability and repeatability. The main function of Y wave-guide is polarizing, coupling and modulating the phase. Phase… (More)
