Abstract

Superresolution is very important in imaging and optical storage systems, and has attracted much attention. In this article, concentric three-zone phase plate with 0, pi, 0 phase variation has been investigated numerically to show that this kind of phase plate can be used to obtain three dimensional superresolution. Focal depth, focal shift, full width half maximum, superresolution effect are listed for different radii of the phase zones, which paves the way for design of the phase plate, such as for purpose of radial superresolution with high focal depth in optical storage.
