| 摘 要： | 采用远心离轴三反成像系统的空间遥感仪器前有光束限制装置时,要求系统具有实入瞳与之匹配。为了满足这一需要,研究了孔径光阑位于主镜前与系统物方焦平面重合的离轴三反系统的设计问题,推导了主镜和三镜共面时离轴三反系统结构参数计算式及物方焦点与主镜间隔表达式,确定了实现系统物方焦点为实焦点的条件及其解法。据此,针对光谱范围为1.0～2.5μm、F数为4、有效焦距为360mm、视场为5°的设计要求,设计出整个波段全视场像质接近衍射极限的具有实入瞳的远心离轴三反系统,系统非球面最高次数为4次。设计结果表明,这种设计方法可用于实入瞳远心离轴三反成像系统的设计。

| Abstract: | If in the telecentric off-axis three-mirror imaging system there is a beam-limited device in front of space remote instrument,a real entrance pupil to match is required.To meet this need,optical design of off-axis three-mirror system whose aperture stop coincides with the object focal plane in front of the primary mirror is studied.The expressions of configuration parameters and the interval between the object focus and the primary mirror of off-axis three-mirror system are deduced in case that the primary ... |
