Abstract
With the rapid development of information technology, people's demands for large-angle coverage and high-information acquisition of optical systems are increasing in industrial production and daily life. Therefore, the requirements for imaging quality of wide-angle lenses are improving. Aiming at solving the severe aberrations in the design of the wide-angle lens, traditional optical designs often introduce complex structures. However, a complex structure will bring several drawbacks such as large volume, heavyweight and high cost. Computational imaging technology(CIT) takes information-driven as the core, breaks the imaging mode of independent optimization of optical design and image restoration, realizes global integrated optimization design, and breaks the limit of traditional imaging. Based on the CIT theory, a simple wide-angle optical system design method is proposed and demonstrated in this paper. Firstly, in the optical design process of the wideangle lens, the requirements for suppressing aberrations are relaxed, and the image quality is worse. Then, the cross-channel image restoration algorithm is used to remove the residual aberrations to obtain a high-quality image. Finally, the system is simplified. This method can not only obtain high-quality images but also reduce the complexity of a wide-angle optical system.
