Abstract
Certain examples relate to a terrestrial terahertz imaging system. In one example, the terrestrial terahertz imaging system has an imaging assembly to form a first image of at least a portion of an object using electromagnetic radiation in a terahertz band of frequencies and a receiver assembly comprising a cryostat. The cryostat contains a detector and reflective cold re-imaging optical components to receive the electromagnetic radiation from the imaging assembly. The reflective cold re-imaging optical components form a second image of at least a portion of the object on the detector. The imaging assembly has reflective optical components arranged in a confocal configuration that is arranged to image at finite conjugates. The reflective cold re-imaging optical components implement a reflective, confocal optical relay. Other examples relate to body and vehicle scanning devices that may be used in security applications.
