An Automatic Laser Collinmation System on Fiber

本文分析了影响激光准直精度的主要因素，提出了相应的改进措施，介绍了自动读出的单模光纤激光准直的原理和系统结构，最后给出了系统在各种条件下的实验结果。

Abstract In this paper, the major factors to affect the accuracy of laser collimationare analysed. The relevant methods to improve the accuracy of laser collimation are put for-ward. The principle of automatic single mode fiber laser collimation and the construction ofthe system are introduced, the experiments on various conditions were made on the system,the results are given out finally. The relative accuracy(3σ)with 0.5 × 10-6 to 2.5 × 10-6within the range of 20 meter in one hour is obtained by the system.
