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 μm. 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.
