Double-view-angle extensible millimeter wave three-dimensional holographic human body imaging equipment

Abstract

The invention discloses double-visual-angle extensible millimeter wave three-dimensional holographic human body imaging equipment, which comprises an equipment panel, a bottom plate device and a display control device, and is characterized in that the equipment panel is fixed on the bottom plate device, and the display control device is connected with the equipment panel; the equipment panel comprises a shell, a multi-view millimeter wave receiving and transmitting array, a vertical support, a driving device and a connecting device, the vertical support is vertically arranged in the shell, and the multi-view millimeter wave receiving and transmitting array is movably connected to the vertical support; the driving device is in transmission connection with the multi-view millimeter wave receiving and transmitting array through the connecting device, and the driving device drives the multi-view millimeter wave receiving and transmitting array to freely move in the vertical direction along the vertical bracket; the multi-view millimeter wave planar array is adopted, the detection imaging of multiple views is achieved in one-time scanning through a single-side array, the number of scanning blind areas is small, and the equipment detection rate is improved.

Description

technical field [0001] The invention relates to the technical field of security inspection, in particular to a dual-view expandable millimeter-wave three-dimensional holographic human body imaging device. Background technique [0002] Common human security inspection equipment mainly includes metal detectors, trace detectors, micro-dose X-ray transmission / backscatter imaging equipment and passive millimeter wave / terahertz imaging equipment. [0003] Specifically, metal detectors are based on electromagnetic eddy current or weak magnetic field detection technology, which can only detect metal substances. Trace detectors are based on the principle of ion mobility and are only effective for explosives and narcotics detection. Micro-dose X-ray transmission / backscatter imaging equipment is based on X-ray transmission / backscatter imaging technology, which can detect metals, non-metals, explosives, drugs, etc., and has high spatial resolution and long Scanning speed, but X-ray si...

AI Technical Summary

Problems solved by technology

The planar scanning equipment adopts horizontal array, the number of array units is small, the equipment cost is low, and the volume is moderate. It is especially suitable for narrow security inspection passages. However, one scan can only obtain images of the front and back of the human body, and the detection rate is low.

Planar sparse array imaging equipment is small in size and fast in scanning and imaging, but it can only obtain images of two perspectives of the front and back of the human body in one scan, and the detection rate is low; secondly, the number of sparse array units is large and the equipment cost is high, which is not conducive to Large-scale promotion and use

[0007] In addition, the three types of millimeter-wave imaging equipment mentioned above all require two front and rear arrays to work together, which cannot realize single-sided imaging, and the equipment cost is high, which is not conducive to the use in occasions that require low equipment cost and low security inspection speed
