Patent ID: 7626400

Claim:
An imaging system, comprising: a housing adapted for movement over an object plane, at least one sensor coupled to the housing for generating data indicative of locations and orientations of the housing over said object plane, wherein said housing comprises: a source of electromagnetic radiation for 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 the 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.
