| Abstract: | Two imaging modes and development of optical synthetic aperture are presented briefly in this paper. The current development situation of three kinds of optical synthetic aperture: segmented mirror, sparse aperture and phased array are introduced comprehensively. This paper also summarized the development trend of ground-based and space-based optical synthetic aperture system and the technical problems. Comparing with traditional single aperture optical system, optical synthetic aperture system has higher resolution, low processing difficulty of mirror, easy folding, light weight, and some other characteristics. So it is an important and effective way to realize high resolution optical imaging system. |
