Abstract:
1. An imaging system, comprising a housing adapted for positioning on a surface, said housing comprising: 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 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 the optical system for receiving radiation therefrom and/or directing radiation thereto, said scan mechanism effecting the scanning of the focused radiation over a two-dimensional portion of the object plane, said housing, optical system, and scan mechanism remaining translationally stationary relative to said surface as said scan mechanism effects the scanning of the radiation, 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 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, wherein said scan mechanism comprises two rotatable refractive elements and said refractive elements comprise a plurality of transmissive prisms, each of said prisms being configured to rotate about a respective rotation axis, and wherein said axes are perpendicular to the bisector of the respective vertex angles of said prisms.
