The invention discloses millimeter wave / terahertz wave imaging equipment. The equipment comprises a quasi-optical component and a millimeter wave / terahertz wave detector array, wherein the quasi-optical component comprises a polyhedral rotating mirror, a third reflecting plate, a fourth reflecting plate and two ellipsoid reflectors, and a reflecting plate is arranged on each side face of the polyhedral rotating mirror and can rotate around the rotating axis of the polyhedral rotating mirror, so that two of the reflecting plates serve as the first reflecting plate and the second reflecting plate in turn to receive and reflect a beam which is self-radiated or reflected by a to-be-detected object; the two ellipsoid reflectors are the same and symmetrically arranged with the polyhedral rotating mirror as the symmetry axis, one ellipsoid reflector is suitable for reflecting th beam from the first reflecting plate to the third reflecting plate, and the other ellipsoid reflector is suitable for reflecting the beam from the second reflecting plate to the fourth reflecting plate; the millimeter wave / terahertz wave detector array is suitable for receiving the beam reflected by the third reflecting plate and the fourth reflecting plate. The millimeter wave / terahertz wave imaging equipment can realize a large field angle and a constant light path aperture, and compared with a transmissiontype, the equipment is free of color difference and low in energy loss.
Description
technical field [0001] The present disclosure relates to the field of imaging technology, in particular to a millimeter wave / terahertz wave imaging device. Background technique [0002] Under the current increasingly severe anti-terrorism situation at home and abroad, terrorists use hidden methods to carry dangerous items such as knives, guns, and explosives with them, posing a serious threat to public safety. The human body security inspection technology based on passive millimeter wave / terahertz wave has unique advantages. It realizes imaging by detecting the millimeter wave / terahertz wave radiation of the target itself, without active radiation, and performs security inspection on the human body. Penetration capability enables detection of hidden dangers. However, existing millimeter-wave / terahertz-wave imaging devices work inefficiently. Contents of the invention [0003] The purpose of the present disclosure is to solve at least one aspect of the above-mentioned pro...
