| 摘 要： | 从像差理论出发，提出一种平像场无遮掩两反射镜系统的设计方法，能够同时消除球差、慧差、像散和场曲四种初级像差.描述了该方法的设计过程和步骤，并总结了这种系统的结构特点. 利用该方法设计出了视场角分别为6°×6°和20°×1°两个光学系统，其成像质量均达到了衍射限.该系统结构简单，易于装调，在航天遥感领域有很大的应用前景.

| Abstract: | Based on aberration theory,the design idea of flat field unobstructed two-mirror system is presented.In this system, spherical aberration,coma,astigmatism and field curvature are free.Designing method and process is described and characteristic of system is summarized.Two systems are designed with the field of view of 6°×6° and 20°×1° and the image quality is in limit of diffraction.The configuration is simple and alignment is convenient.This system is very valuable for space sensing field. |
