摘要
空间三轴激光陀螺的每一个腔长控制器控制两个通道的腔长,即其不同通道的光路稳频具有耦合关系,要实现空间三轴陀螺的工程化应用,必须解决空间三轴激光陀螺的稳频问题。针对空间三轴激光陀螺的稳频回路进行详细的分析,提出了一种稳频方案,该方案将空间三轴激光陀螺的稳频解算为三个通道单轴激光陀螺的稳频问题,其核心思路是对光路稳频关系进行等效变换。经过试验验证,该稳频方案可行有效。
Frequency stabilization for orthogonal triaxial laser gyro is quite difficult,because each cavity path controller controls two cavity paths. It's quite necessary to find out the solution,frequency stabilization accuracy may limit the orthogonal triaxial laser gyro's practical use. The frequency stabilization loop is analyzed in this paper,and a frequency stabilization method for orthogonal triaxial laser gyro is introduced,the frequency stabilization problem for orthogonal triaxial laser gyro turns into the problem for three single laser gyros frequency stabilization,the frequency stabilization transformation is the key procedure. Experiment result shows the method in this paper is useful.
