【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。更多还原

【Abstract】 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.更多还原
