Paper Abstract

A diffractive superresolution element placed at the exit pupil can effectively increase the resolving power of an optical system for optical data storage. The theory of linear programming is suggested in this paper to design the diffractive superresolution elements, which can get globally optimal solutions. Examples of design and some limits of optical superresolution are presented, and a comparison between the results for a uniform incident field and those for a Gaussian incident field is performed.
