传统的光学系统的分辨率正比于光学系统的通光口径。但是增大通光口径会使系统成本增加,给制造、检验和装调带来很大困难,而且增大通光口径还要受到加工水平的限制。因而,不能没有限制地通过增大通光口径来提高系统的分辨率。综合孔径光学系统是解决这一问题的有效途径。本文对综合孔径技术的基本原理进行了阐述,并从理论上论证了用它实现超分辨率的可行性。
The resolution of a traditional optical system is proportional to the optical aperture of the optical system. However, increasing the diameter of the light-passing system will increase the cost, to manufacturing, testing and loading caused great difficulties, and increase the pass-through diameter but also by the processing level of the restrictions. Therefore, the resolution of the system can not be increased without limitation by increasing the aperture. Integrated aperture optical system is an effective way to solve this problem. This paper describes the basic principle of synthetic aperture technology, and theoretically demonstrates the feasibility of using it to achieve super-resolution.
