然后我们再做微小的调整，到焦点的另一边轻微散焦后，看衍射圈质量是否有明显的提高。

Then I make a micro adjustment and go to the other side of focus and see if it has gotten better or worse for that side.

Then I make a micro adjustment and go to the other side of focus and see if it has gotten better or worse for that side. Remember what I said about variables and no free rides?

由于光的衍射作用，使通过聚焦系统的激光束入射到特定靶面成一光斑（主光斑） ，而在主光斑以外还有次级光斑圈（旁瓣）。

The laser beam passing through the focusing systems gets an facula, which consists of main spot and sidelobe on the focus plane.
