In this paper, we describe how a single pixel camera was constructed using widely available components, with the most important component being a repurposed video projector. A single pixel camera uses one single sensor, i.e. one pixel, to read light instensity. This single sensor samples different combinations of parts of the image multiple times, and uses that data to construct the final image. The image quality is primarily determined by the number of times this sampling process is performed, but also by the algorithm used to reconstruct the final image. Both the hardware and software components used for the build are described in this paper. We also discuss the limitations of our prototype, and how it could be improved given better hardware components, and/or improved software.
