A single pixel camera based on compressed sensing

ORAL

Abstract

Digital micromirror devices have proven to be a commercially viable MEMs technology for the video/projector display market. Inspired by the success of this technology, we have combined a microcontrolled mirror with a single optical sensor so that it additionally acquire images, rather than merely adapt current camera technology to serve as an optical sensor. In this project, we have developed a practical image/video camera based on this concept and realized it through the use of \textit{compressed sensing}. Our design has additional desirable properties including scalable output bit stream, variable image resolutions and video frame rates. We will also discuss the generalization of \textit{compressed sensing} as a way of image formation for other single detector systems.
