In the process of work, the laser was reflected by the mirror at first, then turntable adjusted the reflection direction through changing the Angle of azimuth and pitching for accurately pointing.
单反射镜结构转台中，通信光先经反射镜反射，再配合方位、俯仰方向的角度调整，实现光轴的精确对准。

But the biggest problem was the Angle that they were set at, a small deviation in the azimuth and direction created a variety of incorrect readings.
但是最大的问题是他们设置的角度，一些小的角度及方向的误差可以导致很多不正确的读数。
