摘　　要：本文介绍一种提高激光准直精度的新技术。这种技术的基础是建立在激光束的漂移在一定的条件下可以近似的用三角函数去描述它。求出它在有效工作区内各相关点的漂移量f(l)_(?)。通过现已普及使带的计算机技术找出测量点l上的漂移量f(l)_(?),实现测量点的误差补偿。达到提高测量及找正精度的目的。这项技术在工程应用中具有较多的灵活性和方便性。The purpose of the paper is to introduce a new technique of improving the laser alignment accuracy which is built on the basis that the laser beam drift can he described by trigonometrical functions under the certain conditions. The drift volume f(l)_t of cach related point in a effective work area can be calculated. Finding the function f(l)_t of each measured point in the length l, we can compensated the error of the measured point with the computer technique. So the measure and alignment accuracy can he improved. This technique is more flexible and convenient.
