Abstract

In this presentation we show a field of view super-resolution ability while using shifts in time to deal with the diffraction limit as well as the limited density of sampling in space caused due to the stringent size of camera’s pixels/pitch (geometric resolution limit). Using a low-resolution camera, we were able to achieve a high-resolution image by complying with certain conditions that we defined. For that end, we utilized a setup of sub-pixel shifts and grating shifts by time multiplexing, in addition to field of view multiplexing that overcame the diffraction related resolution reduction. The generation of the sub-pixel shifts needed for the operability of the proposed super resolving concept is achieved using DLP device. Improving optical systems resolution is extremely valuable mission in various fields of science and engineering. It helps researchers and industrial companies alike to leap forward the efficiency and ability of their microscopes, telescopes, imaging satellites and aerial photography.
