摘　　要：为了提高平行光管分划板的安装精度,提出一种基于数字干涉仪的平行光管分划板安装方法,介绍了该安装方法的原理和实施过程。以口径800 mm,焦距20 m的平行光管为例,分析并计算了该安装方法和已有安装方法的安装精度。结果表明,该方法对任意分划板的安装精度优于0.07 mm,远高于已有安装方法的安装精度。In order to improve installation accuracy of collimator reticle, an installation method based on dig- ital interferometer is proposed. Principles and implementation processes of the method are introduced. Installa- tion accuracy of this and existed methods are analyzed and calculated based on a collimator with 800 mm aper- ture and 20 m focal length. The results show that installation accuracy of this method for any reticle is better than 0.07 mm, which is much higher than that of existed methods.
