分析了自适应光学系统中高速倾斜反射镜的机械谐振现象及其对控制稳定性和控制带宽的影响。

The mechanical oscillation of the fast steering mirror in adaptive optics system and its effect on control stability are discussed in this paper.

通过将横向剪切干涉仪光路展开，得出反射镜角度变化与干涉条纹倾斜角和线对数变化之间的关系。

By unfolded the Lateral Shear Interferometer, the relationship between the line pairs and the tilt of strip with the tilt of reflected mirrors was derived.

该方案只使用平面反射镜，对于运动部件的精度要求比较低，对倾斜、磨损等不敏感。

This method requires only plane mirrors, and it is immune to tilt, wearing etc.
