In order to decrease the weight of tracking system and make suitable use of the Lander space, the pitching-axis of Lunar optical telescope is vertical with the Lander's flank, its rotation part is fastened on the Lander's flank, the azimuth-axis adopts rotation reflecting mirror, the flat mirror is located before the telescope tube, the angle of flat mirror and the telescope ray-axis is 45°,so that the reflecting ray can enter the telescope optical system, the scan of the mirror can be accomplished by the rotation of the telescope tube.

工作过程中望远镜支架的两个轴需带动望远镜一起转动，为了减小跟踪平台的重量和合理利用着陆器空间，又能在大范围内对太空目标进行跟踪，月基天文望远镜的俯仰轴垂直于着陆器的侧面，其转动部分固联在着陆器的侧面，方位轴采用旋转反射镜方式，将平面反射镜放在望远镜的镜筒前端，并与望远镜光轴成45°安装，使反射光线能够进入望远镜光学系统，通过转动望远镜镜筒使得反射镜实现对空间的扫描。

To further study this problem, the optical axis is rotated by an arbitrary angle. A striking phenomenon is discovered that the Brewster angle is always equal to the rotation angle. This is because the waves in the direction perpendicular to the optical axis become evanescent since the permittivity is positive while the permeability is negative in this direction.

然后进一步的研究了主轴不垂直于界面的情况，发现主轴转动的角度恰好等于此时的Brewster角，这是因为此时垂直于主轴的方向上介电常数为正磁导率为负，只有倏逝波而没有可传播的波存在，因此反射系数为0。
