摘要
研究了受激布里渊散射光纤陀螺 (SBS- FOG)敏感环中 ,在保偏光纤熔接点处进行θ角的偏振主轴旋转后传输光的偏振稳定性。得出当 θ=90°时 ,在敏感环中的传输光不仅具有最大偏振度 ,而且还使其中的两个本征偏振态 (ESOP)达到稳定的结论。
The characteristics of the eigen state of polarization (ESOP) of the pump light and the stimulated Brillouin scattering light in the sensing coil were theoretically analyzed for the stimulated Brillouin scattering fiber optic gyros (SBS FOG), and the conclusions about stability of the ESOP and polarization degree of the transmitting light were obtained.
