The utility model discloses millimeter wave/terahertz wave imaging equipment. Included are: a quasi-optical component, the reflecting plate comprises a V-shaped reflecting plate and a third reflectingplate, the V-shaped reflecting plate comprises a first reflecting plate and a second reflecting plate; the V-shaped reflecting plate can swing around the swing axis of the V-shaped reflecting plate so that the first reflecting plate can receive and reflect wave beams from the parts, located at different positions of the first field of view, of the first detected object, and the second reflectingplate can receive and reflect wave beams from the parts, located at different positions of the second field of view, of the second detected object. The chopper is configured to be incident to the detector array only from the beam reflected by the first reflecting plate or the third reflecting plate at any moment, and the chopper rotates around the central axis of the chopper so that the beam fromthe first reflecting plate and the beam from the third reflecting plate can be alternately received by the detector array. The equipment can image two detected objects at the same time, the detectionefficiency is high, and the utilization rate of the detector is high.
