Paper Abstract

Superoscillation is a promising method to realize superresolution imaging. Nevertheless, in the point spread function (PSF) of previous superoscillation imaging systems, compared to the several orders of magnitude higher intensity in side-lobes, the extremely small intensity in the focal-spot is a severe constraint for practical applications. In this paper, we creatively segment the conventional superoscillation lens into two simple-fabrication portions to generate the superoscillation optical field and realize superresolution imaging in a local field of view (LFOV). We then analyze the contribution of different portions of the entrance pupil to the system’s resolution and propose a novel superoscillation element (NSOE) design to effectively reduce the intensity of side-lobes. We end by reporting our recent results on the imaging of complex targets, and the validity and potential applications of superresolution imaging is well demonstrated.
