摘要
理论分析了四频差动激光陀螺中由于镜片的Ｓ－Ｐ相位和Ｑ的各向异性及光束不过水晶片光轴等因素所引起的左、右旋偏振模式间的差分损耗。这种差分损耗会导致激光陀螺中零漂的形成。
This paper presents a theoretical study of the loss difference between the left and right elliptically polarized modes in differential laser gyro (DILAG), which is caused by the S P phase and Q anisotropy of the cavity mirrors and the off axial propagation of the laser in the quartz crystal. This loss difference could cause unexpected null shifts of the DILAG and the study about it would be an important reference in improving the DILAG operation.
