Abstract:
1. A system for imaging an object, the system comprising: at least one terahertz transmitter for transmitting a plurality of terahertz pulses through or reflected from the object; means for collecting the plurality of terahertz pulses and imparting a different time delay on each of the plurality of terahertz pulses, wherein the collecting means comprises a mask having a plurality of pixels, each pixel receiving one of the plurality of terahertz pulses; a single terahertz detector for receiving each of the plurality of terahertz pulses having different time delays and generating electrical signals corresponding to each of the plurality of terahertz pulses having different time delays; memory means for storing the electrical signals outputted by the terahertz detector; and means for processing the stored electrical signals in the memory means, wherein the processing means is electrically coupled to the memory means and calculates an image of the object.
