By the examples below, and in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail. In the description, same or analogous drawing reference numeral represents same or analogous parts. Following it is intended to the explanation of this utility model embodiment with reference to accompanying drawing overall utility model of the present utility model design is made an explanation, and is not construed as a kind of restriction of the present utility model.

Fig. 1 schematically shows the millimeter wave 3D hologram scanning imagery equipment 100 according to an embodiment of the present utility model. This millimeter wave 3D hologram scanning imagery equipment 100 may include that the first millimeter wave transceiving module, described first millimeter wave transceiving module include the first millimeter wave transceiving aerial array 11 for sending and receive the first millimeter-wave signal and the first millimeter wave transceiver 101 associated with described first millimeter wave transceiving aerial array 11; Second millimeter wave transceiving module, described second millimeter wave transceiving module includes the second millimeter wave transceiving aerial array 12 for sending and receive the second millimeter-wave signal and the second millimeter wave transceiver 102 associated with described second millimeter wave transceiving aerial array 12; First track-type facilities 103, described first millimeter wave transceiving module 101 is can be connected to described first track-type facilities 103 it is thus possible to scan track along described first track-type facilities 103 with first and move the first side 21 of object to be measured and the second side 22 are scanned in the way of sliding; Second track-type facilities 104, described second millimeter wave transceiving module 102 is can be connected to described second track-type facilities 104 it is thus possible to scan track along described second track-type facilities 104 with second and move the 3rd side 23 of described object to be measured and the 4th side 24 are scanned in the way of sliding, 3rd side 23 of described object to be measured is relative with the first side 21 of described object to be measured, and the 4th side 24 of described object to be measured is relative with the second side 22 of described object to be measured; With driving device 30, be used for driving described first millimeter wave transceiving module 101 to move along described first track-type facilities 103 and driving described second millimeter wave transceiving module 102 to move along described second track-type facilities 104. Described first track-type facilities 103 at least extends along the first side 21 of object to be measured and the second side 22, and described second track-type facilities 104 at least extends along the 3rd side 23 of object to be measured and the 4th side 24.

Skilled artisan would appreciate that, first millimeter wave transceiver 101 associates with described first millimeter wave transceiving aerial array 11, represent that the first millimeter wave transceiver 101 electrically connects and collaborative work with the first millimeter wave transceiving aerial array 11, for instance the first millimeter wave transceiver 101 provides millimeter-wave signal for the first millimeter wave transceiving aerial array 11 and the millimeter-wave signal received by the first millimeter wave transceiving aerial array 11 is carried out signal processing. Similarly, the implication that the second millimeter wave transceiver 102 associates with described second millimeter wave transceiving aerial array 12 also should be able to be readily appreciated by one skilled in the art, and does not repeat them here.

In embodiment of the present utility model as shown in Figure 1, described first scanning track and the second scanning track are L-shaped track, and namely the first millimeter wave transceiving module and the second millimeter wave transceiving module are scanned each along L-shaped track. Two adjacent sides of object to be measured (such as human body or article) can be scanned by each millimeter wave transceiving module. So, the sweep limits of two millimeter wave transceiving modules just can cover four sides of object to be measured (such as human body or article). This when need not object to be measured rotate (such as need not human body turn round) or be mobile just can realize the inspection of contraband suspicion thing at full visual angle. Meanwhile, the scan mode of this pair of L-shaped track can adopt rectangular rail (or combination of two L-shaped tracks), more suits human body contour outline, reduces the floor space of equipment, is particularly conducive to use in the place of the limited space such as airport, subway.

Exemplarily, the first track-type facilities 103 and the second track-type facilities 104 can arrange L-shaped track or be formed by a part for rectangular rail. In one example, the scanning direction of described first millimeter wave transceiving module 101 and the scanning direction of the second millimeter wave transceiving module 102 are horizontal direction and described first millimeter wave transceiving aerial array 11 and described second millimeter wave transceiving aerial array 12 each along vertical direction extension. Adopting horizontal sweep mode, it is possible to adopt the first vertical millimeter wave transceiving aerial array 11 and the second millimeter wave transceiving aerial array 12 to be scanned around object to be measured, scanning track is arranged in horizontal plane. This mode is conducive to the layout of equipment and object to be measured to enter and leave this equipment conveniently and efficiently. In one example, in Fig. 1 indicated by arrow, the scanning direction of described first millimeter wave transceiving module and the scanning direction of the second millimeter wave transceiving module are opposite each other. This such as can so that in scanning process the first millimeter wave transceiving module and the second millimeter wave transceiving module be not at position facing each other in the most of the time, to reduce the interference between the first millimeter wave transceiving module and the second millimeter wave transceiving module. But this is not necessarily, for instance, described first millimeter wave transceiving module and the second millimeter wave transceiving module can also adopt identical scanning direction.

In one example, described first scanning track and the second scanning track can combine and form the closing track around object to be measured. This can ensure that four periderm the first millimeter wave transceiving modules of object to be measured and the sweep limits of the second millimeter wave transceiving module are completely covered.

In one example, as in figure 2 it is shown, described driving device 30 may include that driving wheel 31,32,33,34, transmission band rope the 35, first slide 36 and the second slide 37. Described transmission engages to move under the driving of driving wheel 31,32,33,34 with described driving wheel 31,32,33,34 with rope 35, and described first slide 36 and the second slide 37 are connected with described first millimeter wave transceiving module 101 and the second millimeter wave transceiving module 102 and are installed on transmission band rope 35 respectively.

Exemplarily, driving wheel 31,32,33,34 can rotate under driving the driving of axle and drive motor. Although having illustrated four driving wheels 31,32,33,34 in Fig. 2, but in embodiment of the present utility model, the quantity of driving wheel is not limited to this, it would however also be possible to employ one, two, three or more than four driving wheels. When adopting multiple driving wheel, it is possible to setting all of driving wheel and be drivewheel, it is also possible to one of them or some driving wheels are set to drivewheel, all the other driving wheels are set to driven pulley. Such as, in the figure 2 example, it is possible to setting driving wheel 31 and 33 is drivewheel, and driving wheel 32 and 34 is driven pulley. When adopting multiple drivewheel, these drivewheels can work independently, it is also possible to cooperates together.

Although Fig. 2 having illustrated a transmission band rope 35, but embodiment of the present utility model being not limited to this, for instance two or more transmission band ropes can be arranged. When adopting a plurality of transmission band rope, exemplarily, the first slide 36 and the second slide 37 can be respectively arranged in different transmission band ropes. But, the first slide 36 and the second slide 37 can also be installed on same transmission band rope. First slide 36 and the second slide 37 are installed on same transmission band rope, first millimeter wave transceiving module and the second millimeter wave transceiving module will be moved by same transmission band strap, and this advantageously ensures that the synchronizing moving of the first millimeter wave transceiving module and the second millimeter wave transceiving module in scanning process. First slide 36 and the second slide 37 are for being connected to the first millimeter wave transceiving module and the second millimeter wave transceiving module on transmission band rope respectively, so that the first millimeter wave transceiving module and the second millimeter wave transceiving module can be scanned work under the drive of driving wheel.

Exemplarily, described transmission can be the parts being implemented for above-mentioned transmission agency known in the art such as belt, cable with rope 35. Transmission with rope 35 while realizing transmission, also the scanning motion for described first millimeter wave transceiving module and the second millimeter wave transceiving module provides certain constraint, for example, it is possible to make described first millimeter wave transceiving module and the second millimeter wave transceiving module to move at an equal rate.

In another example, if the first slide 36 and the second slide 37 are respectively arranged on different transmission band ropes, then can the scanning motion of independently controlled first millimeter wave transceiving module and the second millimeter wave transceiving module. Such as, the different side of object to be measured or different local are likely to need to be scanned with different fine degree, and this can take into account the accuracy and efficiency of detection. In this case, so that it may so that the first millimeter wave transceiving module and the second millimeter wave transceiving module are scanned at different rates. Exemplarily, transmission can be constant with rope 35 speed in a scan, it is also possible to being variable, the latter can realize the first millimeter wave transceiving module and the variable-speed scanning of the second millimeter wave transceiving module, provides more motility for detection work. Exemplarily, it is also possible to by for the restriction of the transmission direction of motion with rope make the first millimeter wave transceiving module and the second millimeter wave transceiving module along in the same direction or reverse scan move.

In fig. 2, the first track-type facilities 103 and the second track-type facilities 104 define an overall straight-flanked ring rail. Fig. 2 also show the fixing device 81,82,83 and 84 of four corner portions being positioned at this straight-flanked ring rail. This fixing device 81,82,83 and 84 may be used for being fixed on the housing 1 of millimeter wave 3D hologram scanning imagery equipment 100 by the first track-type facilities 103 and the second track-type facilities 104, to keep stablizing of the first track-type facilities 103 and the second track-type facilities 104. Driving device 30 as shown in Figure 2 can be provided only on top or the bottom of the housing 1 of millimeter wave 3D hologram scanning imagery equipment 100. Same driving device 30 can also be respectively provided with, to improve the stability of scanning at the top of the housing 1 of millimeter wave 3D hologram scanning imagery equipment 100 and bottom.

In one example, this millimeter wave 3D hologram scanning imagery equipment 100 can also include data processing equipment 107. Data processing equipment 107 and the first millimeter wave transceiving module and/or the second millimeter wave transceiving module wireless connections or wired connection are to receive from the scanning data of the first millimeter wave transceiving module and/or four sides for object to be measured of described second millimeter wave transceiving module and to generate millimeter wave hologram image. This millimeter wave 3D hologram scanning imagery equipment 100 can also include display device 109. Display device 109 is connected with data processing equipment 107, for receiving and showing the millimeter wave hologram image from data processing equipment 107.

In one example, data processing equipment 107 may be used for generating control signal and sending control signals to driving device 30 to drive the first millimeter wave transceiving module and/or the second millimeter wave transceiving block motion. In another example, millimeter wave 3D hologram scanning imagery equipment 100 can also include and the control device 40 of described data processing equipment 107 phase independence.

Exemplarily, at least one in described first millimeter wave transceiving aerial array 11 and described second millimeter wave transceiving aerial array 12 is provided with the string transmitting antenna and string reception antenna arranged that miss one another. Such as, this row reception antenna can arrange, with this row transmitting antenna, half antenna size but in the vertical direction misplaces that is arranged in parallel. When aerial array works, each moment only one of which transmitting antenna and its adjacent reception antenna work. Switched by electrical switch, it is possible to achieve the quick scanning of vertical direction. Millimeter wave transceiving system adopts the scan method of stepped frequency continuous wave, and frequency sweeping ranges can be 27-33GHz, and frequency scanning is counted and determined by maximum image-forming range.

Exemplarily, in the work process of the first millimeter wave transceiving module and the second millimeter wave transceiving module, Millimeter-Wave Source can produce two-way millimeter-wave signal, and object to be measured, as launching signal, is sent millimeter wave by amplifier and transmitting antenna by a road; Another road is as reference signal, and the millimeter-wave signal received with reception antenna is mixed, and obtains millimeter wave holographic data by I/Q demodulation. Exemplarily, the first millimeter wave transceiving module and the second millimeter wave transceiving module can adopt identical millimeter wave rate of scanning.

Alternatively, in order to reduce the signal disturbing between the first millimeter wave transceiving module and the second millimeter wave transceiving module, in one example, the first millimeter wave transceiving module sends and receives the first millimeter-wave signal and the second millimeter-wave signal of the transmission of the second millimeter wave transceiving module and reception can adopt different frequencies. Or, in another example, in the whole process that object to be measured is scanned by the first millimeter wave transceiving module together with the second millimeter wave transceiving module, the moment that the first millimeter wave transceiving aerial array in first millimeter wave transceiving module and the second millimeter wave transceiving aerial array in the second millimeter wave transceiving module launch millimeter wave is different, namely launches millimeter wave during difference. This can also weaken or be avoided the signal disturbing between the first millimeter wave transceiving module and the second millimeter wave transceiving module.
