Abstract

The general super-resolving theories for Gaussian beam have been investigated. The three-zone amplitude pupils and phase-only pupils are adopted to provide specific numerical descriptions of improvement of DOF, respectively. Simulated results of comparison between Gaussian beam and Uniform amplitude beam have been presented. Furthermore, some useful advices for the design of super-resolving pupils to increase DOF of the optical system based on Gaussian beam are given.
