Multi-visual-angle X ray safety check device

Abstract

The invention discloses a multi-visual-angle X ray safety check device adopting 3 visual angle layout structure; ray sources corresponding to 3 visual angles are all located below a transfer channel of the device; the 3 visual angles are respectively located at the left side, the middle part and the right side of the lower side of the transfer channel; the 3 visual angles are composed of the 3 groups of X ray sources and detectors; each group of X ray source and detector forms a detection unit, wherein the detection units are a left side bottom-illuminating visual angle module, a right side side-illuminating visual angle module and a middle part bottom-illuminating visual angel module arranged below the transfer channel; the left side bottom-illuminating visual angle module comprises a left side bottom-illuminating X ray source and a first detector; the right side bottom-illuminating visual angle module comprises a right side bottom-illuminating X ray source and a second detector; the middle part bottom-illuminating visual angel module comprises a middle part bottom-illuminating X ray source and a third detector. The multi-visual-angle X ray safety check device has the advantages of strong check ability, fast check speed, high detection sensitivity, accurate detection, and strong capacity of resisting disturbance.

Description

technical field [0001] The invention relates to a multi-view X-ray safety inspection device, which belongs to the technical field of X-ray imaging safety inspection. Background technique [0002] At present, the implementation of security checks on luggage carried by people passing through important entrances and exits has become a security measure widely used in the world. For luggage security checks, X-ray security check devices are currently the most widely used type of non-contact security checks. Devices. In recent years, X-ray security inspection devices have been developed rapidly driven by the safety needs of aviation, railways and customs. The earliest X-ray security inspection devices used single-view single-energy X-ray technology. This type of inspection device is usually mainly composed of a single X-ray generator, collimator, detector, channel, conveyor belt and box. When the system is working, the conveyor belt will send the luggage to be inspected into the c...
