Abstract

The invention discloses millimeter wave holographic imaging equipment capable of executing relative cylindrical surface scanning. The millimeter wave holographic imaging equipment comprises a first arc sliding rail support and a second arc sliding rail support, and arc upper rails and arc lower rails with arc sliding rails with restricted arc trajectories which are mutually parallelly arranged at the top parts and the bottom parts of the first arc sliding rail support and the second arc sliding rail support, wherein arc trajectories restricted by the arc sliding rails of the first arc upper rail and the second arc upper rail located at the upper side form a group of relative non-concentric arc trajectories; and a first vertical millimeter wave transmitting and receiving device and a second vertical millimeter wave transmitting and receiving device are arranged between the arc upper rails and arc lower rails along a vertical direction and can slide along the arc sliding rails of the arc upper rails and arc lower rails. The first vertical millimeter wave transmitting and receiving device and the second vertical millimeter wave transmitting and receiving device comprise a millimeter wave transmitting and receiving antenna array for receiving and transmitting millimeter wave signals. The first vertical millimeter wave transmitting and receiving device and the second vertical millimeter wave transmitting and receiving device are separated mutually and arranged relatively, and thus, space for object detection is formed between the two. A turntable shift fork is also arranged to drive the first vertical millimeter wave transmitting and receiving device and the second vertical millimeter wave transmitting and receiving device to move along the arc sliding rails respectively.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to millimeter wave holographic imaging equipment. Background technique [0002] At present, the known millimeter-wave detection and imaging equipment adopts a cylindrical scanning method. The scanning trajectory of the cross section is circular, while the cross section of the human body is elliptical. Therefore, the scanning overlap is not high, resulting in The intensity consistency is poor, resulting in poor image imaging effect; the detector is hung vertically at a single point, the stability is poor, and the image shakes during movement, resulting in blurred images; in addition, the image imaging effect is poor, and the equipment adaptability is not good. [0003] It is desired to provide an inspection device with strong adaptability and improved imaging effect. Contents of the invention [0004] To solve the problem that the imaging of the inspection equipment in...
