Abstract

In this paper, we propose a subpixel-shifted method to overcome the limitations on the resolution of an image obtained from single-pixel imaging system. In the proposed method, modulation system is moved by sub-integer low grid units, and new information contained in each shifted low grid area can be exploited to obtain a high-resolution image. The front and back modulation single-pixel imaging systems are analyzed. Based on the shifted and point spread function parameters, this method using compressed sensing algorithm can overcome the limitative resolution generated by the modulation system pixel size and transmission effect to get high-resolution image. Finally, the machining experiment results prove the effective of the proposed method.
