Abstract

A new set of tunable phase-only filters for realizing the transverse superresolution is introduced. The filters, whose significant features are their ability to tune and simplicity, consist of one half-wave plate between two quarter-wave plates, and the half-wave plate is made of two zones that can rotate with respect to each other. Through analyzing the transverse point spread function of such system, it can be concluded that by rotating any zone of the half-wave plate, the transverse resolution can be realized and can be tunable.
