摘　　要：研究四频差动激光陀螺的稳增益控制技术,建立陀螺增益的物理模型,并分析误差因素。设计通过稳光强来稳增益的方案。实验结果表明,室温下稳光强模式和传统稳流模式相比,四频差动激光陀螺的开机零漂减小0.001 6°/h,长时间零漂减小0.002 9°/h。这对于陀螺性能改善有一定参考价值。The gain stabilization control technology of four frequency differential laser gyro is studied systemati- cally. Physics model of the gyro gain is built, the error influence is analyzed. Scheme of gain stabilization through light intensity stabilization is designed. Experiment results indicate that： compared with traditional current stabiliza- tion under normal temperature environment, light intensity stabilization can decrease the startup drift by 0. 001 6°/ h, decrease the long term drift by 0. 002 9°/h. The result can be helpful to the improvement of the performance of four frequency differential laser gyro.
