Based on the Hartmann testing principle, this paper proposes a novel image quality testing technology which applies to a large-aperture space optical system. Compared with the traditional testing method through a large-aperture collimator, the scanning Hartmann testing technology has great advantages due to its simple structure, low cost, and ability to perform wavefront measurement of an optical system. The basic testing principle of the scanning Hartmann testing technology, data processing method, and simulation process are presented in this paper. Certain simulation results are also given to verify the feasibility of this technology. Furthermore, a measuring system is developed to conduct a wavefront measurement experiment for a 200 mm aperture optical system. The small deviation (6.3%) of root mean square (RMS) between experimental results and interferometric results indicates that the testing system can measure low-order aberration correctly, which means that the scanning Hartmann testing technology has the ability to test the imaging quality of a large-aperture space optical system.
基于哈特曼测试原理，本文提出了一种适用于大口径空间光学系统的新型图像质量测试技术。与传统的通过大口径准直器的测试方法相比，扫描哈特曼测试技术具有结构简单、成本低以及能够对光学系统进行波前测量的优点。本文介绍了扫描哈特曼测试技术的基本测试原理、数据处理方法和仿真过程。还给出了一定的仿真结果以验证该技术的可行性。此外，开发了一个测量系统对一个200毫米口径的光学系统进行波前测量实验。实验结果与干涉测量结果之间的均方根（RMS）小偏差（6.3%）表明测试系统能够正确测量低阶像差，这意味着扫描哈特曼测试技术有能力测试大口径空间光学系统的成像质量。
