介绍了一种新的基于径向波前斜率的哈特曼检测方法及原理,并重点介绍了采用该方法和技术研制的800 mm口径的径向哈特曼像质检测实验系统的组成及结构,以及利用该系统对700 mm光学系统像质检测的实验结果。研究表明,在没有昂贵的大口径标准平面镜的情况下,用该方法在室内可实现大型望远镜系统的像质检测。 A new Hartmann detection method and principle based on the radial wave front slope are introduced, and the composition and structure of the 800 mm radial Hartman image detection system developed by the method and technology are emphatically introduced , As well as the experimental results of using this system to detect the image quality of a 700 mm optical system. The research shows that this method can be used to detect the image quality of large-scale telescope system indoors without expensive large-caliber standard plane mirror.
