Abstract

The invention discloses the millimeter wave holographic imaging equipment that can perform relative column scans. The millimeter wave holographic imaging equipment includes: the first and second arc -shaped slide -shaped sliding rail support; the top and the bottom of the first and second arc -shaped sliding rail branches The arc -shaped upper rails and arc -shaped lower rails of the arc -shaped slide with a limited arc -shaped trajectory are arranged. The limited arc -shaped trajectory constitutes a relatively non -concentric arc -shaped trajectory. First, the second vertical straight millimeter wave receiver device is arranged between the upper rail and the lower rail of the arc, and the arc -shaped slide rails that can follow the arc -shaped upper rail and the curved lower rail. First, the second vertical millimeter wave receiving device includes a millimeter wave income antenna array for sending and receiving millimeter wave signals. First, the second vertical millimeter wave sending device is separated from each other and relative settings to form a space for checking objects between the two. The rotary fork is also set to move the first and second vertical direct millimeter waves and sending device along the rounded skate 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...
