The present invention discloses a detection device for discriminating between different materials, and a method for doing so. The device comprises an optical system having at least one optical focussing element and a receiving element. The receiving element is sensitive to electromagnetic radiation, typically in the millimetre wave band, and the optical system being arranged to focus incident energy from a scene onto the receiving element. The optical system comprises a prism element having a first surface and a second surface, the first surface being opposite the second surface. At least a portion of the first surface is positioned at an angle θ to the second surface. The angle θ varies between a minimum at a first position on the first surface and a maximum at a second position on the first surface.
A detection device for discriminating between different materials, comprising an optical system having at least one optical focussing element, an optical scanning element and a receiving element, wherein the receiving element is sensitive to electromagnetic radiation, the optical system being arranged to focus incident energy from a scene onto the receiving element via the optical scanning element, wherein the optical scanning element has a first surface having a region with a continuously variable angle with respect to a second surface of the optical scanning element, wherein the continuously variable angle acts to provide a continuously variable scan of the scene.
A detection device as claimed in any of the above claims wherein the device is arranged to detect radiation produced by the target, or radiation reflected from the target emanating from the surrounding environment.
Method of detecting objects present in a scene by means of receiving electromagnetic radiation from the scene, comprising:
