Abstract

This paper presents a system that exceeds the Rayleigh limit of resolution by placing three fixed gratings in predetermined positions. The proposed system works without any moving elements and is suitable for coherent or incoherent two-dimensional imaging. The three gratings are located between the input plane and the output plane, and thus the superresolved image is produced without additional imaging lenses. The generalized gratings allow us to obtain the undistorted spectral restoration of information. The trade-off for higher resolution is a smaller field of view. Experiment results validate the theoretical analysis.
