Research on a simple longfocus optical modality using optical/image co-design method

In view of the computational imaging theory, a simple long-focus optical system design method with the optical/image co-design is proposed and demonstrated in this paper. Based on the idea of global optimization, this method considers the two independent links of optical design and image restoration as a whole. The imaging quality requirements in the optical system design are relaxed at the front end, and the image restoration algorithm is used to remove the residual aberrations in the back end. This method can not only obtain the same or even higher imaging performance, but also reduce the complexity of the optical system.
