Abstract

The super-resolution imager based on the coded aperture is a novelty technology. It breaks the constraints of conventional optical imager in techniques and principles. The spatial resolution of the optical system is increased 1-fold than the conventional system. In this paper, we have studied and analyzed the principle of super-resolution imager based on coded aperture. We can add a high robust coded aperture in the stereotyped low-resolution camera to achieve improvement of the original camera image resolution. In order to fully prove the advantages, we have designed a complete and easy-to-experiment optical system based on the principle of the system.The Optical system focal length is 90mm. It is coaxial optical path and its total length is 538.5mm. The MTF value is near the diffraction limit at 56lp / mm. We can obtain good quality images by the system.Laboratory experiments verify that the spatial resolution of the optical system is 1 times higher than that of the conventional ones.
