A 2D camera design with a single-pixel detector

A single-pixel camera for THz imaging has been proposed in. In this article, we propose a new design for a single-detector THz imaging system based on compressive sampling (CS), which does not need raster scanning of the object in front of the THz beam. We exploit a time-efficient and cost-effective design to acquire the CS measurements. As a result, the image acquisition time in the proposed imaging system is only limited to the speed of the THz detector. The proposed approach is applicable to other types of imaging as well.
