摘要

摘要: 为了同时实现成像系统的大视场、长焦距和高分辨率,设计了基于同心球透镜的四镜头探测器阵列拼接成像系统.首先,阐述了四镜头探测器阵列拼接方案的原理;介绍了同心球透镜的结构特点,阐述了其成像优点.然后,完成了满足实际拼接应用的同心球广角、长焦成像系统(拼接子系统)的光学设计.最后,给出了拼接子系统的像质评价并对其进行公差分析.结果表明:拼接后的系统可实现100 mm焦距和120视场成像.该系统解决了大视场和长焦距之间的矛盾,可实现超高像素成像,相对于传统光电成像系统具有巨大的优势.

Abstract: In order to achieve both wide field of angle and high resolution in one imaging device, we propose a method which combines detectors arrays mosaic technique and monocentric imaging lens. This paper first introduces the scheme of detectors mosaic of four lens systems, and next there is a thorough discussion of advantages by adopting monocentric objective lens. After that, a completed lens design prescription is presented as well as the related specifications. In the final part, evaluation of the imaging quality is discussed along with the tolerance sensitivity analysis. The finished system has 120 FOV and 100 mm focal length. As depicted, the contradiction between wide field of angle and long-focus has been figured out excellently by the monocentric mosaic imaging system which can complete ultra-high resolution imaging and has great advantage compared with other imaging devices.
