Fig. 1 is the skeleton view of the millimeter wave 3D hologram scanning imagery equipment diagrammatically illustrated according to disclosure embodiment.
As shown in Figure 1, this millimeter wave 3D hologram scanning imagery equipment can comprise conveyer 6 and at least one millimeter wave transceiving module (4,5).
Conveyer 6 is for such as, along first direction traffic bit object (not shown, human body or article) thereon.In this example, first direction is the direction shown in arrow 9 in figure.Conveyer 6 can be implemented as various ways, such as travelling belt or rotating ladder etc.
Millimeter wave transceiving module (4,5) can comprise the millimeter wave transceiving aerial array 52 for sending and receive millimeter-wave signal, as shown in Figure 2.Millimeter wave transceiving aerial array 52 can comprise multiple millimeter wave emitting antenna 53 and multiple millimeter wave receiving antenna 54.In the figure 2 example, multiple millimeter wave emitting antenna 53 is depicted as row, and multiple millimeter wave receiving antenna 54 is depicted as row, these two row are arranged in parallel.But the arrangement of millimeter wave transceiving aerial array 52 is not limited thereto.According to design needs, differently can arrange millimeter wave transceiving aerial array 52.Such as, in millimeter wave transceiving aerial array 52, the row of millimeter wave emitting antenna 53 and the row of millimeter wave receiving antenna 54 can be alternately arranged, or arrange multiple millimeter wave emitting antenna 53 in a region and arrange multiple millimeter wave emitting antenna 53 in another region, etc.Each array antenna can be arranged in parallel, and the antenna in adjacent column need not be aimed at completely.
The surface of emission of millimeter wave transceiving aerial array 52 and receiving plane can be in roughly same plane, thus millimeter wave transceiving module (4,5) can carry out flat scanning, but not cylinder scanning.Compared with cylinder scanning, the millimeter wave holographic imaging algorithm required for flat scanning is more simple and accurate.
Millimeter wave transceiving module (4,5) can also comprise the millimeter wave transceiving circuit 51 being connected with millimeter wave transceiving aerial array 52 and cooperatively interacting.Particularly, this millimeter wave transceiving circuit 51 can be arranged in millimeter wave transceiving module (4,5) and after millimeter wave transceiving aerial array 52.Be appreciated that, as long as can guarantee that millimeter wave transceiving circuit 51 does not block the transmitting-receiving of millimeter wave, this millimeter wave transceiving circuit 51 can be arranged on arbitrary position, such as millimeter wave transceiving module (4,5) above or below or the left side or the right side.
It is other that millimeter wave transceiving module (4,5) is arranged on conveyer 6, and make when conveyer transmission object is through each millimeter wave transceiving module, this millimeter wave transceiving module can scan object.At this, millimeter wave transceiving module (4,5) is set to towards conveyer 6, thus its efficient working range can cover the certain area on conveyer.Like this, when object is conveyed through millimeter wave transceiving module (4,5) by conveyer 6, the millimeter wave that millimeter wave transceiving module (4,5) sends can incide on object, and can receive the millimeter wave from object reflection.According to the millimeter wave from object reflection, the scan-data of object can be obtained, and obtain the millimeter wave hologram image of object accordingly.
Millimeter wave transceiving module (4,5) is set to it and longitudinally extends along intersecting the second direction of (such as, vertically) with first direction.In common safety check occasion, human body or article direction of transfer (that is, first direction) can be approximate horizontal directions, and now the longitudinal direction of millimeter wave transceiving module (4,5) can extend along roughly vertical direction.At this, so-called " longitudinal direction ", refers to the prolonging direction of millimeter wave transceiving module (4,5).Under normal circumstances, the longitudinal direction of millimeter wave transceiving module (4,5) corresponds to the direction that the millimeter wave transceiving aerial array that comprises in this module can scan by switching transmit/receive antenna, and this will further describe following.Usually, millimeter wave transceiving module (4,5) is extended along this direction of scanning, thus millimeter wave transceiving module (4,5) is called as " length " in the dimension in this direction, and therefore this direction is referred to as " longitudinal direction ".The direction of the longitudinal normally row of millimeter wave emitting antenna 53 and/or the row of millimeter wave receiving antenna 54.
In the example of fig. 1, two millimeter wave transceiving modules 4 and 5 are shown.These two millimeter wave transceiving modules 4 and 5 are separately positioned on the relative both sides of conveyer 6.Like this, they can scan the not homonymy (left side such as, in Fig. 1 and right side) of the object on conveyer 6 respectively.This can significantly improve checking efficiency.
It should be noted that, although illustrated the situation that millimeter wave transceiving module 4 and millimeter wave transceiving module 5 are arranged opposite to each other in Fig. 1, the disclosure has been not limited thereto.Such as, millimeter wave transceiving module 4 and millimeter wave transceiving module 5 can spaced apart certain distances on first direction (direction in figure described in arrow 9).And for example, if in order to obtain better image effect from certain specific orientation (front, side of such as object or proceeds posterolateral etc.), millimeter wave transceiving module 4 and/or millimeter wave transceiving module 5 can not be arranged to just to conveyer 6, but tiltedly to conveyer 6.And millimeter wave transceiving module 4 and millimeter wave transceiving module 5 are also not limited to extend along identical direction, but can extend along different directions (that is, can have multiple different second direction).
The disclosure is also not limited to arrange two millimeter wave transceiving modules, but can arrange single or three and even more millimeter wave transceiving modules.When arranging single millimeter wave transceiving module, scanning single side can be carried out to object, or object can be overturn to realize bilateral scanning in scanning process; And when arranging three and even more millimeter wave transceiving modules, can scan from more sides and/or more perspective object.
Be appreciated that for the imaging of millimeter wave 3D hologram, require that scanning has three dimensions: a dimension in two dimensions spatially and frequency.This scanning that two dimensions are spatially the scanning of first direction respectively---this scanning can be realized by the translatory movement of conveyer 6, and the scanning of second direction---can by switching current emitting antenna and/or current reception antenna realization.In addition, the scanning in frequency dimension then can be realized by the millimeter wave frequency changing transmitting and receiving.
When longitudinally the extending along equidirectional of millimeter wave transceiving module 4 and millimeter wave transceiving module 5, their respective direction of scanning identical (that is, there is same second direction).In this case, such as, the image of the different angles of the same local obtaining object is the most in time easy to.When longitudinally the extending along different directions of millimeter wave transceiving module 4 and millimeter wave transceiving module 5, their respective direction of scanning differences (that is, there is different second directions).This can make in scanning process, and they are not in position facing each other, therefore, can reduce the interference between millimeter wave transceiving module 4 and the second millimeter wave transceiving module 5.
In addition, millimeter wave transceiving module 4 and millimeter wave transceiving module 5 can synchronously be carried out along the scanning of respective second direction, synchronously to present 3D hologram image.Alternatively, millimeter wave transceiving module 4 and millimeter wave transceiving module 5 can be carried out asynchronously along the scanning of respective second direction, because the not homonymy of object can have different scanning requirements.Such as, certain side of object or certain local can need more meticulous scanning, and other positions of object only may need the scanning of rather rough.In this case, nonsynchronous point of other control can be adopted to millimeter wave transceiving module 4 and millimeter wave transceiving module 5.Equally, millimeter wave transceiving module 4 and millimeter wave transceiving module 5 also can have different sweep velocitys, to be adapted to different scanning requirements.Even the sweep velocity of millimeter wave transceiving module 4 and millimeter wave transceiving module 5 can be consecutive variations or intermitter change.
In scanning process, the movement of conveyer 6 can be along first direction stroboscopic motion or move continuously.
In one embodiment, in scanning process, conveyer 6 stroboscopic motion, for the same position residing for object, current emitting antenna in the millimeter wave frequency of being launched by change, change millimeter wave transceiving module (4,5) and/or receiving antenna are to carry out the scanning of two dimensions to object.The scanning of these two dimensions, in conjunction with the stroboscopic motion of conveyer 6, obtains the scan-data of three complete dimensions.
In another embodiment, in scanning process, conveyer 6 moves continuously or uninterruptedly moves, while conveyer 6 movement, by changing millimeter wave frequency, the change millimeter wave transceiving module (4 of launching, 5) the current emitting antenna in and/or receiving antenna to carry out the scanning of three dimensions to object, thus obtain the scan-data of three complete dimensions.
Like this, in scanning process, millimeter wave transceiving module (4,5) can be fixed.Therefore, without the need to arranging moving component, thus compact structure can be realized in millimeter wave transceiving module (4,5).
Certainly, millimeter wave transceiving module (4,5) also can comprise position adjusting mechanism, such as, be arranged in its base, thus can realize millimeter wave transceiving module (4,5) carries out in orientation and angle adjustment relative to transmitting device 6.So, direction of scanning can be adjusted as required, and at this moment cylinder scanning cannot realize.
In one example, this millimeter wave 3D hologram scanning imagery equipment can also comprise data processing equipment 2.Data processing equipment 2 and (4, the 5) wireless connections of millimeter wave transceiving module or wired connection (such as by wire 8), generate millimeter wave hologram image with the scan-data received from millimeter wave transceiving module (4,5).In scanning process, millimeter wave transceiving module (4,5) scan-data obtained can be real-time transmitted to data processing equipment 2, or segment transmissions, to data processing equipment 2, or is disposablely transferred to data processing equipment 2 after cushioning after buffering.Data processing equipment 2 after receiving all scan-datas, can obtain millimeter wave hologram image by process; Or immediately can process after receiving partial data.
This millimeter wave 3D hologram scanning imagery equipment can also comprise display device 1.Display device 1 and data processing equipment 2 wirelessly or by wire (such as by wire 7) are connected, for receiving and showing the millimeter wave hologram image from data processing equipment 2.
Alternatively, data processing equipment 2 can carry out the identification of automatic suspicion thing to the millimeter wave hologram image generated, and recognition result is transferred to display device 1, thus display device 1 can show millimeter wave hologram image and suspicion thing recognition result.When recognizing suspicion thing, can also on millimeter wave hologram image the approximate location of the suspicion thing of Identification display.
In one example, data processing equipment 2 can generate control signal and control signal is sent to conveyer 6, to make conveyer 6 in a controlled manner (such as, with certain speed; Continuous motion or stroboscopic motion, etc.) transmission object.In another example, millimeter wave 3D hologram scanning imagery equipment also can comprise and data processing equipment 2 phase independently control device (not shown), and this control device is for generating control signal and control signal being sent to conveyer 6 to realize scanning motion in a controlled manner to make conveyer 6.
In one example, data processing equipment 2 can generate control signal and control signal is sent to millimeter wave transceiving module (4,5), to make millimeter wave transceiving module (4,5) carry out the switching of transmit/receive antenna and/or the switching of frequency in a controlled manner.In another example, millimeter wave 3D hologram scanning imagery equipment also can comprise and data processing equipment 2 phase independently control device (not shown), this control device is used for control signal and control signal is sent to millimeter wave transceiving module (4,5).This control device can be combined in millimeter wave transceiving module (4,5), such as, in millimeter wave transceiving circuit 51.
In order to reduce the interference between millimeter wave transceiving module 4 and millimeter wave transceiving module 5, millimeter wave transceiving module 4 and millimeter wave transceiving module 5 can adopt different frequencies.In addition, millimeter wave transceiving aerial array in millimeter wave transceiving module 4 and the millimeter wave transceiving aerial array in millimeter wave transceiving module 5 launch moment of millimeter wave can be different, thus can reduce the interference between millimeter wave transceiving module 4 and millimeter wave transceiving module 5 further.
In one example, this millimeter wave 3D hologram scanning imagery equipment can also comprise position transducer 3, for sensing the distance of the position of object on conveyer 6, particularly object and millimeter wave transceiving module (4,5).Such as, position transducer 3 can be arranged in corresponding millimeter wave transceiving module (4,5).When object transmits on conveyer 6, along with object is near millimeter wave transceiving module (4,5), when according to the sensing result determination object of position transducer 3 and millimeter wave transceiving module (4,5), when distance is less than predetermined value, instruction can be sent by such as indicating device 10, keep static with reminding object (particularly tested person), so that millimeter wave transceiving module (4,5) can imaging better.In addition, along with object transmits away from millimeter wave transceiving module (4,5), when according to the sensing result determination object of position transducer 3 and millimeter wave transceiving module (4,5) when distance is greater than predetermined value, instruction can be sent by indicating device 10, can be freely movable with reminding object (particularly tested person).If desired, also regulation can be made to stand direction and the posture of tested person.Indicating device 10 such as can be implemented as the pilot lamp that can glimmer.
