20 Claims

1. An imaging device for generating images at a first set of wavelengths in the millimetre and sub-millimetre range, the imaging device comprising: a lens system for generating an image of a sample at a focal plane; one or more detectors, each detector comprising an antenna and associated signal processing means, each antenna being located at the focal plane of the lens system; one or more movable supports on which the one or more antennae are mounted, the supports including drive means for controllably moving the one or more antennae across the focal plane; and a reflector adapted to reflect radiation at a second set of wavelengths, different to said first set of wavelengths, mounted on each antenna.
