通过分析传统激光陀螺的调腔方式,提出了激光陀螺应在实际工作条件(具有增益能力状态)下进行调腔的观点,以及通过控制其腔长或光程长来控制反射镜的反射方向的调腔方法,并相应地设计了新的腔长控制镜结构。通过全面扫描的方式,找出了空间正交三轴激光陀螺的三腔在高质量运转时的最佳角度控制参数,解决了空间三轴激光陀螺高精度调腔的难题。 By analyzing the cavity adjusting method of traditional laser gyro, the view that cavity gyro should be adjusted under actual operating conditions (with gain capability) and the cavity adjusting the cavity length or path length to control the reflecting direction of mirror Method, and accordingly designed a new cavity length control mirror structure. Through the comprehensive scanning method, the optimal angle control parameters of three-cavity space orthogonal three-axis laser gyroscope in high quality operation are found out, which solves the problem of high precision cavity reconciliation in space three-axis laser gyroscope.
