Abstract

A method to increase resolution in single-pixel imaging through parallel implementation based on the selfimaging effect is proposed. The scanning basis, Walsh-Hadamard patterns, are displayed in each unit cell of a 2D binary grating codified on a DMD. The self-imaging effect is used to project the sampling functions onto the object. Images with higher resolution can be obtained by using a light sensor with a low number of pixels and reconstructing by single-pixel technique. This approach can be useful to improve the resolution of IR or THz cameras. Preliminary results are shown.
