设计了一种适于车载等运动环境下的快速控制反射镜
用于在具有振动和冲击的工作环境下控制激光发射系统的激光光束稳定及其精确校准。根据某光学系统的性能指标要求,阐述了用于高能激光的平面反射镜的物理性能以及控制反射镜负载应有的机械特性。采用大行程的音圈电机作为控制反射镜的驱动器,并设计了精度高、抗干扰能力强的角位移测量装置作为控制反射镜的位置传感器。对所采用的4个音圈电机和4个角位移测量装置进行了合理布局,既降低了系统的转动惯量又提高了系统的可靠性和环境适应性。实验结果表明:该快速控制反射镜的定位精度优于1.4″,满足高能激光发射系统对控制反射镜的精度要求。
A Fast Steering Mirror (FSM) suitable for motion environments was designed to control the laser beam stabilization and its accurate alignment for a laser projecting system in the vibration and shocking. According to the requirement of performance of the optical system
the necessary physical and mechanical characteristics of the FSM were presented for the reflecting mirror of a high energy laser. The voice coil actuators with large travels were used as the drivers of the FSM
and angle displacement measuring devices with high precision and anti-jamming ability were taken as the position sensors of the FSM. The four voice coil actuators and four angle position measuring devices were reasonably arranged to decrease the inertial moment of the system and also to improve the reliability and condition adaptability. The experimental result shows that the positioning accuracy of FSM is better than 1.4″
which satisfies the precision requirement of the laser projecting system for the FSM.
