1. An imaging system, comprising:

  • a source of electromagnetic radiation capable of generating radiation with one or more frequencies in a range of about 1 GHz to about 2000 GHz, an optical system optically coupled to said source so as to focus radiation received therefrom onto an object plane, said optical system directing at least a portion of the focused radiation propagating back from the object plane onto an image plane, a scan mechanism coupled to said optical system for controlling thereof so as to move the focused radiation over the object plane, a detector optically coupled to said optical system at the image plane to detect at least a portion of the radiation propagating back from a plurality of scanned locations in the object plane, thereby generating a time-dependent detection signal, and a processor in communication with the detector to generate an image of at least a portion of the object plane based on said detection signal
