Based On Active Optical Imaging Technology For Space Zoom

In recent years, with the rapid development of science and technologies, the demandsof optical zoom systems have become higher for people, which not only have largeview angle, fast zoom speed, but also have light weight, small volume, low powerconsumption. In particular, because of large size, heavy weight, and large energyconsumption for the zoom optical system used in the space, the development of spaceoptics is seriously blocked.Compared with the traditional mechanical zoom imaging systems, the activeoptical zoom system can change the effective focal length without adjusting theseparation between optical elements, thereby reducing the spacing of each device formoving mechanical parts, and then reducing the volume, weight. This optical systemof zoom has high speed, and low energy consumption. And it can realize partial zoom,that is, it can vary the effective length at any partial field of view and at the same timemaintain high resolution over a limited area of interest.The optics spatial zoom imaging technology is investigated based on activeoptics in this paper. Firstly, we introduce the concept, history of the zoom opticalsystem. The background, purpose and significance of this paper are also introduced.We research the development of active zoom optical system in the world, andinvestigate the general theory of active zoom optical system. Then, we investigate theactive optical zoom based on the general theory. Secondly, both three reflectivemirrors active zoom system and an active zoom system with special field of view aredesigned The aberration and imaging quality is analysised.Finally, the experimental work for deformable mirrors is introduced in this article,and a mirror is designed and developed, which can change the curvature.
