構裝過程中最重要也是最為複雜、繁瑣的步驟即為耦合對準的部分，因為這個過程對光耦合效率有最直接的影響，而在對準的過程中，過多參數的調整變化不易同時掌握，所以目前大部分的對準過程中搜尋最高耦合效率位置時，大多藉著減少自由度來簡化對準過程，尤其是角度對準。
本文開發一多軸自動化耦合對準系統時，在觀察模擬結果後發現，對XY平面來說，在角度有誤差的情況下光耦合效率光偶合效率最高的位置並不會改變，故發展出2+2個自由度之搜尋法則，來達到四個自由度(X、Y、θx、θy)之自動化搜尋目標，結果可得到較高之耦合效率與快速之耦合對準過程。

The most complicated and important step in optical packaging is coupling alignment. It is very difficult to handle too many parameters at the same time during the coupling alignment process. Most of the parameters are neglected in coupling alignment process, especially the parameters of angles.
According to the analysis, we found that the misalignment of angles do not have influence on the position of highest coupling efficiency in XY plane. A 2+2 freedom searching method has been developed to reach the four axis coupling alignment. An automatic coupling alignment system has been carried out. And it can reach higher coupling efficiency and faster coupling alignment process.
