    FUNDAMENTALS OF THE INVENTION. 1. Field of Invention
    [0001] The present invention in general relates to a technical field of human body safety inspection, in particular an apparatus for imaging millimeter wave three-dimensional holographic scanning and a method for inspecting a human body or an article using the same. ; 2. Description of the related technique
    [0002] The security imaging inspection technology for a human body or an article widely used today mainly comprises X-ray imaging technology and millimeter wave imaging technology. Millimeter wave imaging technology has become more popular in these years. It can in principle be classified into passive millimeter wave imaging technology and active millimeter wave imaging technology. Holographic imaging technology is the most important millimeter form.
    [0003] three-dimensional of human, raster imaging technology | cylindrical has been used widely. However, cylindrical scanning imaging apparatus has a huge volume and a complex algorithm that is derived through the theoretical approximation process, and thus its imaging accuracy is limited. Furthermore, a cylindrical scan can only use a vertical antenna array which has a large length and many antenna units, thus increasing the cost of the device. )
    [0004] In addition, the active millimeter wave three-dimensional holographic imaging apparatus in the form of single side scan only inspects one side of the human body to be inspected at once and thus, the entire inspection for the human body needs to be carried out two scans. The human body to be inspected needs to rotate around the signal even between two scans such that the safety inspection process becomes complicated and has a slow inspection speed. In the millimeter wave three-dimensional holographic imaging apparatus active in the form of single side scan, once it is turned off or another failure occurs, a millimeter wave transceiver module therein may tend to fall out and may be damaged. In order to prevent it from being damaged, the apparatus needs to be provided with components such as counterweights, internal contraction brakes, shock absorbers, and so on, which cause a high complexity and low reliability of the system.

    [00032] Figure 3 is a flowchart of a method for inspecting a human body or article according to an embodiment of the present invention. j DETAILED DESCRIPTION OF MODALITIES)
    [00033] The technical solutions of the present invention will be described hereinafter in more detail regarding the embodiment with reference to the Figures of the attached drawings, characterized in that the same or similar reference numerals refer to the same) or similar elements from beginning to end of the specification. The explanation for the embodiment of the present invention with reference to the accompanying drawings is intended to interpret the general inventive concept of the present invention, rather than to be interpreted as limiting the present invention.
    [00034] Fig. 1 shows, in schematic form, an apparatus for imaging three-dimensional holographic scanning of millimeter wave 100 according to an embodiment of the present invention. It may include a first millimeter wave transceiver module 101, a second millimeter wave transceiver module 102, | a first guide rail device 103, a second device 104, operating mechanisms 105a, 105b, 105c, 105d and a restrictor 106. The first millimeter wave transceiver module 101 comprises a first millimeter wave transceiver antenna array for transmitting and receiving a first millimeter wave signal, and the first millimeter wave transceiver module 101 is slidably connected with the first guide rail device 103, such that the first millimeter wave transceiver module 101 is movable along the first guide rail device 103 for performing a first scan on an object to be inspected. Likewise, the second millimeter wave transceiver module 102 comprises a second antenna array of ! millimeter wave transceiver for transmitting and receiving a second millimeter wave signal and is slidably connected with the second guide rail device 104 such that the second millimeter wave transceiver module 102 is movable along the second guide rail device. tab 104 to perform a second scan on the object to be inspected.
    [00035] That is, the 100 millimeter wave three-dimensional holographic scanning imaging apparatus according to the present invention can scan the object to be inspected in two orientations at the same time, for example, scanning the side front and a scan of the back side of the object (such as a human body or article) at the same time. This can improve [the inspection efficiency significantly, for example, when the object to be inspected is the human body, the device can scan the front side and the back side of the human body at the same time without needing to rotate around the human body. It will be useful to increase the efficiency of the inspection. It should be noted that the arrangement of the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 facing each other as shown in Fig. 1 is not necessary, for example, if a better forming effect can be achieved in a given orientation, the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 can be arranged not facing each other, but allowing the directions in which they transmit waves millimeters are at an angle to each other. |
    [00036] The operating mechanisms 105a, 105b, 105c and 105d are configured to drive the first millimeter wave transceiver module 101 to move along the first guide rail device 103 and/or to drive the second wave transceiver module millimeter 102 to move along the second guide rail device 104; Fig. 1 shows various operating mechanisms, including a first driver 105a for driving the first millimeter wave transceiver module 101 directly, a second driver 105b for driving the second millimeter wave transceiver module 102 directly, and operating mechanisms l|05c, 105d to drive the first millimeter wave transceiver module 101 and/or the second millimeter wave transceiver module 102 operating the restrictor 106 (in the case shown in Fig. 1, it is a line or belt). However, all of these operating mechanisms are not necessary, for example, the Millimeter Wave Three-Dimensional Holographic Scanning Imaging Apparatus 100 may include only one or some of these operating mechanisms 105a, 105b, 105c and 105d. In the case that more than one of the operating mechanisms is provided, they can | be operated independently or in combination as long as they can drive the first millimeter wave transceiver module 101 and/or the second millimeter wave transceiver module 102 to perform sweeping actions. In the case where the above first driver 105a and/or second driver 105b are/is provided, the first millimeter wave transceiver module 101 can be connected with the first guide rail device 103 via the first driver 105a and/or the second module millimeter wave transceiver 102 can be connected with the second guide rail device 104 via the second driver 105b.
    [00037] The restrictor 106 is configured to constrain the kinematic relationship between the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 such that the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 only or has to move in opposite directions from each other. The restrictor 106 can allow the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 to move in cooperation with each other without further precise control and thus simplifying the system. In addition, restricting the first millimeter wave transceiver module 1Õ1 and the second millimeter wave transceiver module 102 to only move in opposite directions to each other can cause them to be staggered into position rather than facing each other. ü with each other for most of the period during the sweep. Thus, the disturbance between the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 can be reduced compared to the case that they move in the same direction.
    [00038] In one example, the restrictor 106 may also constrain the positional relationship between the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module (102 such that the first millimeter wave transceiver module 101 and the second transceiver module millimeter wave transceiver 102 only move at the same speed. For example, restrictor 106 may be a strap or rigid connection line to connect the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102, as shown in Fig. 1. the so-called rigid connecting line or belt means that the connecting line or belt is substantially inelastic or has a change in length which may be neglected if the line or belt is deformed by a nominal force. rigid connection line is stretched by a pulling force, the belt or connection line between the first millin:electric wave transceiver module 101 and the second millimeter wave transceiver module 102 has a fixed length. Therefore, if one of the first millimeter wave transcyptor module 1O1 and the second millimeter wave transceiver module 102 moves in one direction (for example, in an 'upward' direction), the other of them needs to move in an opposite direction and they have equal movement speed.
    [00039] In order to arrange the belt or rigid connecting line more conveniently, as an example, a fixed pulley can be used. For example, the first guide rail device 103 can be provided with a first fixed pulley 103a and the second guide rail device 104 can be provided with a second fixed pulley 104a. The belt or connecting line can connect the first millimeter wave transceiver module 101 to the second millimeter wave transceiver module 102[ via the first fixed pulley 103a and the second fixed pulley 104a.
    [00040] Although the belt or rigid connecting line is used as the restrictor 106 in the modality as shown in Fig. 1, it is not necessary, as appreciated by the person skilled in the art. Other forms of restrictors 106 may also be used, for example restrictor 106 may be implemented as implemented by pneumatic, hydraulic, magnetic or electrostatic design or other features known in the art. . !
    [00041] In an example, the first guide rail device 103 and the second guide rail device 104 may be substantially parallel to each other. However, it is not necessary, for example, for the sake of convenient arrangement, they can angle each other. In an example, the first guide rail device 103 and/or the second guide rail device 104 may be composed of one rail or a large number of rails in parallel with each other. The latter allows the first millimeter wave transceiver module 101 and/or the second millimeter wave transceiver module 102 to move more stably.
    [00042] In an example, the first millimeter wave transceiver module 101 and/or the second millimeter wave transceiver module 102 can move in a vertical plane. In such a case, due to [the effects of gravity, the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 can be balanced in weight so that they can move more stably. In particular, in the case that they use the belt or connecting line as the restrictor 106, they can also prevent the first millimeter wave transceiver module 101 and/or the second millimeter wave transceiver module 102 from being damaged due to an unexpected drop. when a system failure occurs.
    [00043] In one example, the millimeter wave three-dimensional holographic scanning imaging apparatus 100 may further comprise a data processing device 107. The data processing device 107 is communicated by wire (e.g., by wires 108 ) or wirelessly with the first millimeter wave transceiver module 101 and/or the second millimeter wave transceiver module 102 to receive scan data from the first millimeter wave transceiver module 101 and/or the second millimeter wave transceiver module 102 and to generate a millimeter wave holographic image. The millimeter wave three-dimensional holographic scanning imaging apparatus 100 may further comprise a display device 109. The display device 109 is communicated to the data processing device 107 to receive and display the millimeter wave holographic image from the device. of data processing 107.
    [00044] In an example, the data processing device 107 can be configured to generate a control signal and transmit it to operating mechanisms 105a, 105b, 105c operating mechanisms 105a, 105b, 105c and 105d to drive the first module millimeter wave transceiver 101 and/or the second millimeter wave transceiver module 102 to move. As another example, the millimeter wave three-dimensional holographic scanning imaging apparatus 100 may also include a separate controller with respect to the data processing device 107, the separate controller configured to generate a control signal and transmit it. the operating mechanisms 105a, 105b, 105c and 105d to enable the operating mechanisms 105a, 105b, 105c and 105d to drive the first millimeter wave transceiver module 101 and/or the second millimeter wave transceiver module 102 to effect sweeping motion.
    [00045] In order to reduce the signal disturbance between the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102, as an example, the first (millimeter wave signal transmitted and received by the first wave transceiver module millimeter 101 and the second millimeter wave signal transmitted and received by the second millimeter wave transceiver module 1)02 may have different frequencies in at least 50% of an entire scan period of the object to be inspected by both the first module) transceiver millimeter wave transceiver 101 and the second millimeter wave transceiver module 102, for example, throughout the entire period or portion of the entire period in which the first millimeter wave transceiver module 101 is relatively close to the second millimeter wave transceiver module 102. I
    [00046] In another example, the time that the millimeter wave transceiver antenna array transmits millimeter waves in the first millimeter wave transceiver module 101 may be different from the time that the second millimeter wave transceiver antenna array in the second millimeter wave transceiver module 102 transmits millimeter waves while scanning the object to be inspected by both the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102, that is, they transmit respective millimeter waves at different times . This can also reduce or prevent signal disturbance between the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102.
    [00047] Fig. 2 shows, schematically, the apparatus for image formation by three-dimensional holographic scanning of millimeter wave above when scanning an object to be inspected. The object to be inspected 200 (the human body shown in Fig.2) is located between the first millimeter wave transceiver module 1O1 and the second millimeter wave transceiver module 102. The first millimeter wave transceiver module 1 G 1 and the second millimeter wave transceiver module 102 can respectively scan the front side and rear side of the object to be inspected 200 to obtain data, the data processing device 107 providing for generating millimeter wave images.
    [00048] The present invention further provides a method for inspecting a human body or an article using a three-dimensional millimeter wave holographic scanning imaging apparatus as shown in Fig. 3. The method includes: a step 301 locating the human body or article in an inspection position and setting a first millimeter wave transceiver module 101 and a second millimeter wave transceiver module 102 in their initial scan positions, respectively; a step 302 of driving the first millimeter wave transceiver module 1O1 and the second millimeter wave transceiver module 102 through a driver 105a, 105b, 105c, 105d to move from their scan start positions to their scan end positions along the first guide rail device 103 and the second guide rail device 104 continuously or discontinuously to finish scanning the human body or article; a step 303 of transmitting sampled datai by the first millimeter wave transceiver module 101 and by the second millimeter wave transceiver module 102 during a scan of a data processing device 107, one scan and/or after the scan; and a step 304 of processing the data received from the first millimeter wave transceiver module 101 and from the second millimeter wave transceiver module 102 using the data processing device 107 to generate a millimeter wave holographic image of the human body or article. .
    [00049] In step 302 above, during scanning of the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102, the kinematic relationship between them is restricted by restrictor 106 such that the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 only move in opposite directions with each other. |
    [00050] As described above, during scanning of the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102, the positional relationship between the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 may be constrained by restrictor 106 such that the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 only move at the same speed. Just as described above, as an example, restrictor 106 (may be a strap or rigid connection line for connecting the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102. In step 302 above, the first module millimeter wave transceiver 101 and/or second millimeter wave transceiver module 102 may be operated to move by operating the first millimeter wave transceiver module 101 and/or second millimeter wave transceiver module 102 directly, or may be operated to move by operating restrictor 106.
    [00051] In order to reduce the disturbance of the erythre signal, the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102, the frequency division (the first millimeter wave transceiver module 101 and the second wave transceiver module millimeter wave 102 transmit and receive millimeter waves of different frequencies) or time division (the first millimeter wave transceiver module 101 and the second millimeter wave transceiver module 102 transmit millimeter waves at different times) as described above can be used in step 302 .I
    [00052] In an example, the above method may optionally further include a step 305: after generating the millimeter wave holographic image of the human body or article, perform an auphomatic identification on whether the human body or article contains suspicious objects and about the position of suspicious objects and issue the identified results. With step 305, suspicious objects can be quickly identified to safely avoid risks. This is particularly beneficial in applications (which need to quickly determine security risks, eg airports, and customs. j
    [00053] Although the present invention has been (explained with reference to the drawings, the embodiments shown in the drawings are illustrative only, rather than limiting the present invention. j
    [00054] Although some modalities of the general inventive concept are illustrated and explained, it would be appreciated by those skilled in the art that modifications and variations can be made in these modalities without departing from the principles and spirit of the general concept (inventive of the description, the scope of the which is defined in the appended claims and their equivalents.
