Super-Resolution Imaging Using Compressive Sensing and Binary Pure-Phase Annular Filter

Super-resolution is an important goal for the diffraction-limited optical system. In this paper, we present a novel technique that exceeds the limit of resolving power of the diffraction-limited optical system to achieve super-resolution imaging by combining compressive sensing with a binary pure-ph...

Description
Summary:Super-resolution is an important goal for the diffraction-limited optical system. In this paper, we present a novel technique that exceeds the limit of resolving power of the diffraction-limited optical system to achieve super-resolution imaging by combining compressive sensing with a binary pure-phase annular filter. This novel technique is achieved by using a classical 4F optical system with a pure-phase spatial light modulator. The feasibility of this imaging technique is theoretically analyzed and physically validated by laboratory experiments.
