The device is applied for three dimensional alignment of optical connector module of the standard Intel Light Peak. The database of the relationships of fiber microlens off-axis, tilting and the coupling efficiency is established. 　　The system uses CCD cameras for real-time monitoring. The coupling efficiency can be calculated from the image processing method. A five-axis precision translation stage is used for a platform. It can be adjusted the axis offset and relative angle to obtain the case of optimal coupling efficiency. With a novel algorithm, the system can determine the direction of off-axis or tilt, to search for the best position of the coupling efficiency. Finally the smallest movement of the translation stage can be obtained in the database of the Light Peak coupling efficiency.
