摘要
离轴三反光学系统具有高分辨率、大视场、长焦距、质量轻、小体积等特点,满足空间对地遥感、空间摄影等领域的要求。介绍了离轴三反射镜光学系统的设计原理。用ZEMAX软件设计了一个三个反射面均是二次曲面、焦距为2000mm、F数为9的离轴三反射镜系统。结果表明,该系统可达到7°×3°视场,对于空间频率50lp/mm,调制传递函数值均大于0.5。
The characteristics of uncoaxial three-mirror system are high resolution, wide field of view, long focal length, light weight and small volume. It satisfies the requirement of remote sensing and space photography. The design principle of the uncoaxial three-mirror system is introduced. With the help of ZEMAX software, a uncoaxial three-mirror system is given. It has a focal length of 2 000 mm, F number of 9 and all surfaces are conicoid. It is shown that the system attains a field of view 7°×3° and MTF is higher than 0.5 at 50 lp/mm.
