%X The influence of Kerr effect to close-loop digital resonator fiber optic gyroscope based on squarewave frequency modulation was analyzed in theory. The results show that the Kerr-effect-induced bias relates to the light intensity difference between two inverse lightwaves, and the amplitudes of square-wave frequency modulation of these inverse lightwaves also affect it. Through proper adjustment to frequency modulation amplitude, the Kerr-effect-induced bias can be effectively reduced. This method for Kerreffect-induced bias reduction utilizing the characteristic of square-wave frequency modulation, need without any additional optical devices, has low intensity modulation frequency requirement. And it is a effective method for Kerr-effect-induced bias reduction in close-loop digital R-FOG.
