摘要

以同心多尺度成像模式为基础，结合人眼视网膜凹成像思想，提出了一种宽视场与双分辨率成像组合的新型同心多尺度成像系统，在广域视场范围内实现了对关注的感兴趣目标区域的高分辨动态注视。介绍了同心多尺度双分辨率成像系统的工作方式；使用一个单透镜和一个双胶合透镜为初始结构，结合二轴微机电系统（MEMS）扫描微镜组合形成光路；利用ZEMAX光学设计软件，优化设计了成像波段为0.486~0.656

m，在单个分通道视场内（30°）可对关注的小视场区域（6°）高分辨注视跟踪的子成像系统。对成像系统的像质以及点列图、调制传递函数（MTF）曲线、场曲、畸变曲线进行了评价。结果表明设计的子成像系统在全视场内成像均匀，接近衍射极限，场曲和畸变较小，最大场曲不超过0.6 mm，最大畸变小于1.5%，能够满足同心多尺度双分辨率成像系统对子成像系统性能的要求。

Abstract

A new monocentric multiscale imaging system with a wide field of view and dual resolution was proposed based on the theories of monocentric multiscale imaging and foveated imaging to achieve the high resolution dynamic gazing of the interesting region in a wide-area. The working model of this system was described in detail. By using a single lens and a doublet as the initial structure

two axis MEMS(Micro-Electronic-Mechanical System) micro mirrors were combined to form a light path. On the basis of the ZEMAX software

a sub-imaging system(6°) was optimized and designed to realize the high resolution gazing in the individual separated field of view(30°) at the spectra range from 486-0.656

m. The image quality

spot diagram

Modulation Transform Function(MTF) curve and the field curvature/distortion curve of the sub-image system were evaluated

and the results show that the imaging is uniform in the full field of view and approaches the diffraction limitation. Moreover

it has smaller field curvature and distortion

the field curvature is smaller than 0.6 mm

and the distortion is smaller than 1.5%. These data meet the requirements of monocentric multiscale dual resolution imaging systems for the performance of sub-imaging systems.
