Description
Technical field
The utility model belongs to the safety inspection technical field, specifically more relates to a kind of rays safety detection apparatus of realizing single source various visual angles rotation sweep.
Background technology
Safety inspection is at anti-terrorism, dangerous act such as hit that traffic in drugs smuggling and contraband goods are carried; Has crucial meaning; For example in the big assembly exhibition; Occasions such as airport station terminal are carried out safety inspection to people's luggage and articles, container etc. and are seemed very necessary to prevent that harm from producing.
Realize there are following several kinds usually in the rays safety detection apparatus of safety inspection at present:
Be illustrated in figure 1 as and adopt the single visual angle X ray article to be had an X-rayed the rays safety detection apparatus of scanning; The scan mode of this kind equipment comprises that radiographic source a sends flying spot; Conveyor b sends into luggage c in the transfer passage with certain speed, and the fan-shaped x-ray beam of process collimation passes the luggage on the travelling belt.Detector module d receives the X ray signal that is produced after the absorbed; System's control and signal processing circuit unit are accepted detectable signal and are handled; Result sends the overall treatment computing machine to, in the overall treatment computing machine, obtains the image of seized luggage after process computing and the imaging processing.This kind single-view X ray safety inspection equipment is for each regional shape facility judges whether to have known violated thing in the picture signal through observing.Its shortcoming is, this equipment just adopts the single-view through-transmission technique, because the image that obtains is a two dimensional image, many materials are that overlapping back shows, can have the situation of leaking the thing of finding to violate a ban.
Be illustrated in figure 2 as the equipment that adopts the double vision angle to carry out the luggage safety inspection, it utilizes two visual angle X ray that article are carried out transmission scan.Radiographic source e sends flying spot, and conveyor f sends into luggage g in the transfer passage with certain speed, and the fan-shaped x-ray beam of process collimation passes the luggage on the travelling belt.Two detector module h receive the X ray signal that is produced after the absorbed; System's control and signal processing circuit unit are accepted detectable signal and are handled; Result sends the overall treatment computing machine to, in the overall treatment computing machine, obtains the image of seized luggage after process computing and the imaging processing.The shortcoming of this kind equipment is that only projection is carried out at other a fixing visual angle of employing, still has the situation of finding violated thing of leaking.
The equipment that utilizes the CT technology to carry out the safety of goods inspection is also arranged; Conveyor transports luggage forward with certain speed; Meanwhile; X-ray source and detector module rotate with certain speed under the driving of structure continuously; Fan-shaped x-ray beam through collimation passes the luggage on the travelling belt, and detector module receives the X ray signal that is produced after the absorbed, and system's control and signal processing circuit unit are accepted detectable signal and utilized backprojection algorithm to rebuild the faultage image and the three-dimensional image of examined object.
More than can find out; When utilizing CT scan equipment that large-volume objects is carried out the CT tomoscan; General method all is to adopt the scan mode of rotation+translation, and promptly radiographic source, detector rotate around central shaft, and inspected object moves along the direction that is parallel to turning axle; Therefore the complex structure of CT equipment makes cable kink problem together because of overcoming continuous rotation.
And for the bigger object in transversal section; If hope accurately to carry out image reconstruction; Just need carry out the projection of big measuring angle; Transmission imaging causes the efficient of safety inspection all very low fast, and this is intolerable for exhibition, harbour, the passenger flow transport field that all need carry out the large numbers of items inspection every day.
In addition, for perspective imaging, if with the beam parallel direction a plurality of article are being arranged, then article are mutual superposition in image, are difficult to accurately differentiate article generally speaking, bring very big difficulty for the discovery of prohibited items.
