英文摘要：

The collectivity compositions and characteristics of the high-precision laser collimator system were presented. The commutation rule and the optimal collimation area are analyzed when Gauss light beam passes thin lens, and the design principles of the collimator are given. Main specifications, software for straightness error evaluation, and two methods for the measurements of straightness error in dynamic ＆ static states are given. By utilizing the developed evaluation software, the system was tested experimently and also its application foreground is also prospected.
