提高激光准直精度的途径

在激光准直高精度直线度测量中，激光漂移是影响其测量精度的主要因素。激光光线漂移分为光漂、光线弯曲和随机抖动三种类型，针对不同的产生漂移的原因，需采取适当的补偿方法来解决激光漂移问题，提高激光准直测量精度。本文对不同类型提高激光准直精度的方法进行了归纳，并分析了各方法的优缺点。

Methods of Improving Accuracy of Laser Collimation

laser drift is the major factor that affects the accuracy of the propagating direction of a laser beam, There are three kinds of laser drift, light beam drift, light bend and stochastic turbulence. We need to use different methods according to different kinds of laser drift, The principle and characteristics of different methods are summarized.
